3 Description

The XTR200 is a high-voltage, precision, output driver for 3-wire current or voltage systems, designed for standard industrial signal levels such as 0mA to 20mA, 4mA to 20mA, and 0V to 10V. The mode pin configures the device for either current or voltage output and eliminates the need to change external components to switch between modes. In current- output mode, the ratio between input voltage and output current is set by a single resistor, R SET. In voltage-output mode, the XTR200 has a fixed gain of 3.75V/V which is set by integrated, high-precision, thin-film, resistors. The device integrates a low-leakage PMOS output transistor and short-circuit current protection, further reducing the need for external components. An external PNP or PMOS transistor can be used with the XTR200 to reduce on-chip power dissipation. The on-chip short-circuit protection also protects external transistors from damaging overcurrent events. The XTR200 error flag pin ( EF) indicates several temperature or output fault conditions. The output disable pin (OD) places the output pin into a high- impedance state with very low leakage. The XTR200 is available in a small 3mm × 2mm, 10-pin WSON surface-mount package.

6 Detailed Description

6.1 Overview

The XTR200 is an output driver intended for 3-wire systems with analog current or voltage outputs. The XTR200 is designed to deliver the commonly-used industrial signaling ranges of 0mA to 20mA, 4mA to 20mA, or 0V to 10V on a single supply and with minimal additional components. The performance is specified for a nominal supply voltage of 24V, but sustained supply voltages up to 60V are acceptable, with an absolute maximum supply voltage rating of 65V. Furthermore, the XTR200 is specified over the full industrial temperature range of –40°C to +125°C. The XTR200 has two modes of normal operation. In current-output mode, the voltage-to-current ratio is defined by an external resistor, RSET; therefore, the input voltage range can be freely set in accordance with application requirements. In voltage-output mode, the XTR200 has a fixed gain of 3.75V/V, which produces a 0V to 10V output from a 0V to 2.67V input voltage achievable by many common digital-to-analog converters (DACs) and microcontrollers. Error detection circuitry activates a logic output (error flag pin, EF) in case the correct current or voltage output is unachievable, the die temperature is too high, or the power supply voltage is too low. Use the output disable (OD) pin during power-on, multiplexing, and other conditions where a high-impedance output is required. The OD pin contains an internal pullup that causes the XTR200 to power up in output-disabled mode unless the OD pin is tied low. The XTR200 integrates an output PMOS capable of driving the full rated load current across a wide range of supply voltages. However, the device can also be configured to use an external PNP or PMOS transistor to deliver the majority of the load current and reduce the on-chip power dissipation. Both the internal PMOS and optional external transistors are protected by integrated short circuit protection circuitry.

6.3 Feature Description

6.3.1 Explanation of Pin Functions

INPUT: This input is a conventional, noninverting, high-impedance input of an operational amplifier (op amp). This pin is designed for voltages from 0V to 5V. The internal circuitry is protected by clamp diodes to ground and an internal 5V reference. Applying voltages beyond 0V to 5V causes a large amount of current to flow through the clamp diodes and potentially damage the device. An external series resistor can be used to limit current through the clamp diodes if voltages beyond the 0V to 5V range are expected. MODE: This input determines the output mode of the XTR200. Applying a voltage greater than 1.65V selects current-output mode. A voltage less than 0.8V above ground selects voltage-output mode. This pin has a 4 μA internal pullup current source to 3.3V. EF : The active ‑low error flag (logic output) indicates the fault conditions listed in the Error Flag section. This pin has a 4 μA internal pullup current source to 3.3V. The pin can be used with a pullup resistor to an external voltage source for different voltage levels. Leave the pin unconnected if not used. OD: This control input has a 4 μA internal pullup current source disabling the output. Pulling the pin low, within 0.8V of GND, is required to activate the output. Control OD to reduce output glitches during power on and power off. If not used, connect this pin to ground to enable the output continuously. SET: The total resistance connected between this pin and the ground reference sets the voltage-to-current transfer ratio. Additional series resistance introduced by improper PCB layout degrades precision. The voltage on this pin must not exceed 5V. IS: This output pin is connected to the source or emitter of an external transistor (PMOS or PNP) if one is used. If no external transistor is used, short this pin to the VG pin for proper functionality. VG: This output pin drives the gate or base of an external transistor. Short this pin to the IS pin if no external transistor is used. VSP: This is the positive power supply for the internal circuitry of the XTR200. The XTR200 tolerates supply voltages up to a maximum of 65V, which allows the XTR200 to operate in harsh industrial environments. Use a bypass capacitor (e.g. 100nF) and optionally a damping inductor or a small resistor (5 Ω) to decouple the XTR200 supply from the noise typically found on industrial 24V supplies. GND: The GND pin is both the negative power supply and the reference voltage point for the internal circuitry of the XTR200. The input voltage, logic levels, and R SET voltage are measured with respect to this point. Provide a low-impedance connection to the system ground for reliable operation. OUT: This pin delivers load current from the internal PMOS transistor. If using an external transistor, connect the OUT pin to the collector or drain of the external PNP or PMOS transistor.

6.3.2 Using an External Transistor

The XTR200 integrates an output transistor capable of delivering the specified output current to a wide range of load resistances. However, in applications with high supply voltages, using an external transistor reduces the power dissipated in the XTR200. The Power Supply Recommendations section provides useful information on supply voltage and PCB temperature limitations when using the internal output transistor. Establish that the external transistor is rated for the maximum anticipated supply voltage and is capable of dissipating the power generated by the load current and the voltage drop across the transistor. Figure 6-1 and Figure 6-2 display the current flow when using an external PNP or PMOS transistor with the XTR200. A portion of the load current flows through the internal 1k Ω resistor between the IS and VG pins, producing a voltage which turns on the external transistor. The voltage between the IS and VG pins is limited to approximately 2V by a clamp circuit represented by a Zener diode in the diagram. A small portion of the output load current still flows through the internal PMOS of the XTR200 but is recombined with the current through the external transistor. When using an external PNP transistor, the base current is recirculated through the internal PMOS (Q2) and does not degrade the accuracy of the output current. www.ti.com XTR200 SBOSAL6A – JUNE 2025 – REVISED SEPTEMBER 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 15 Product Folder Links: XTR200

All load current flows through the on-chip 50 Ω resistor in the XTR200 which is used to measure output current and detect fault conditions. For this reason, using an external transistor does not change the transfer function of the XTR200 or increase the maximum output current. External transistors are protected from short-circuit faults by the same circuitry which protects the internal output PMOS. VSP OUT VG IS XTR200 RLOAD Figure 6-1. Current Pathways for an External PNP Transistor VSP OUT VG IS XTR200 RLOAD Figure 6-2. Current Pathways for an External PMOS Transistor

6.3.3 Error Flag

The XTR200 has internal circuitry that detects the error states listed in Table 6-1. When an error state is detected, the error flag EF (an open-drain logic output), pulls low. This digital output can be pulled up to an external logic voltage through a resistor. The internal pullup current is 4μA to an internal 3.3V reference. Table 6-1. Error States Indicated by Error Flag Error State Description Output short Short-circuit current limit reached in voltage-output mode Output open Unable to reach correct output current in current-output mode. This fault condition is only detectable with an input voltage of >350mV and a supply voltage of >10V. Output saturation Insufficient headroom between load voltage and supply voltage to achieve correct voltage or current output. This fault condition is only detectable with a supply voltage of >10V.

6.4 Device Functional Modes

6.4.1 Current-Output Mode

Applying a voltage greater than 1.65V to the MODE pin places the XTR200 into current-output mode. In current-output mode, the XTR200 acts as a voltage-controlled current source. Figure 6-3 shows the internal configuration of the XTR200, as well as the current flow inside the device. When a voltage is applied to the input, amplifier A1 drives the gate of NMOS transistor Q1, which causes a current I SET to flow through the external resistor RSET. The voltage at the SET pin is fed back to the inverting input of amplifier A1 through switch SW1. This feedback loop forces the voltage at the SET pin to equal the input voltage, as shown in Equation 1. I SE T = V IN R SET (1) ISET also flows through the 500 Ω resistor connected between the drain of Q1 and the power supply, VSP. Amplifier A2 senses the voltage drop across this 500Ω resistor and drives the gate of the PMOS output transistor Q2 through switch SW4. This action creates an equal voltage drop across the 50 Ω resistor at the inverting input connected between the source of Q2 and VSP. To produce an equal voltage at the input terminals of amplifier A2, 10 times more current must flow through the 50Ω resistor, as shown in Equation 2 I O UT = 10 × I S ET (2) The general equation for the transfer function in current-output mode is: I O UT = 10 × V IN R SET (3) 500 110k 40k SET MODE INPUT VSP OUT VG IS GND OD XTR200 RSET SW1 SW2 SW3 SW4 EF >2V –VIN ISET IOUT Figure 6-3. XTR200 Internal Configuration and Current Flow in Current-Output Mode

6.4.2 Voltage-Output Mode

Pulling the MODE pin low places the XTR200 into voltage-output mode. Figure 6-4 shows the internal configuration of the device in voltage-output mode. Amplifier A2 is now bypassed and the inverted output of amplifier A1 controls the output transistor Q2 through switch SW4. Switches SW2 and SW3 close the feedback loop through the on-chip voltage divider consisting of 110k Ω and 40kΩ resistors. These resistors are fabricated using a high-precision thin-film deposition and precision layout techniques to deliver extremely low gain error over the full temperature range. www.ti.com XTR200 SBOSAL6A – JUNE 2025 – REVISED SEPTEMBER 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 17 Product Folder Links: XTR200

The on-chip, precision voltage divider determines the transfer function in voltage output mode: V OUT = V IN × 3.75 (4) In voltage-output mode, the gate of transistor Q1 is connected to ground and no current flows from the SET pin. A resistor present at the SET pin, R SET, does not affect voltage output operation. This allows the XTR200 to operate in voltage or current output mode without changing external components. 500 110k 40k SET MODE VSP OUT VG IS GND OD XTR200 RSET SW1 SW2 SW3 SW4 INPUT EF –VIN Figure 6-4. XTR200 Internal Configuration in Voltage-Output Mode

6.4.3 Output Disabled

Applying a voltage greater than 1.65V above ground to the OD pin disables the output of the XTR200. Power supply voltages less than 7.4V also disable the output of the device. Figure 6-5 shows the internal configuration of the XTR200 with the output disabled. In this mode, the gate of the internal output PMOS transistor, Q2, is shorted to the source through an internal switch to make the OUT pin high impedance. The gate of the internal NMOS transistor, Q1, is also shorted to ground so that the SET pin is high impedance. The OUT pin is tolerant of voltages less than the power supply voltage in this state. 500 SET MODE VSP OUT VG IS GND OD XTR200 RSET INPUT EF –>1.65V Figure 6-5.

6.4.4 Thermal Shutdown

The error flag pin ( EF) of the XTR200 indicates a die temperature above 150°C as a warning of a fault condition. If the die temperature continues to rise, the XTR200 enters into a thermal shutdown state when the die temperature exceeds 160°C. In the thermal shutdown state, the output is disabled (high impedance) until the die temperature cools below 150°C. If the external fault condition which initially produced the high die temperature has not been remedied, the device oscillates in and out of the thermal shutdown state until the fault is removed.

7 Application and Implementation

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality.

7.1 Application Information

7.1.1 Input Voltage

The linear input voltage range extends from 0V to 5V. The input voltage is referenced to the grounding point of RSET. Verify that R SET is not distorted from other currents. Assuming a 3V full-scale input signal for a 20mA output current, R SET is 1.5k Ω. A resistance uncertainty of just 1.5 Ω already degrades the accuracy to below 0.1%. Select a precision, low-drift resistor for best performance because resistor drift directly converts into drift of the output current. Design the layout carefully to minimize any series resistance with R SET and the input reference point. Do not drive the input negative (referred to GND) greater than 500mV. Higher negative voltages turn on the internal protection diodes. Insert a resistor in series with the input if negative signals can occur during power on, power off, or other transient conditions. Use a voltage divider to add an offset voltage to the input voltage for a 4mA to 20mA signaling range as shown in Figure 7-1. In this approach, an offset voltage is derived from a voltage reference and voltage divider, such that the XTR200 delivers 4mA to the load when the DAC output voltage is 0V, preserving DAC resolution. VSP GNDSET OUTINPUT MODE EF OD RSET IS VG XTR200 DAC RLOAD 4mAR2 R1Voltage Reference VCC VCC 0V VOS VREF Figure 7-1. Adding an Offset Voltage to the XTR200 Input for 4mA to 20mA Signaling Use Equation 5 to calculate the offset voltage, VOS, required for a 4mA output. V OS = 4 mA × R S ET 10 (5) When the necessary offset voltage is calculated, calculate the values of R1 and R2 using the equation: www.ti.com XTR200 SBOSAL6A – JUNE 2025 – REVISED SEPTEMBER 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 19 Product Folder Links: XTR200

V OS = V REF × R 2 R 1 + R 2 (6) Consider the minimum output voltage of the DAC when designing this circuit. Some DACs do not reach all the way to 0V.

7.1.2 Miswiring Protection

On occasion, miswiring faults occur when field transmitters are installed in industrial environments. If the OUT pin of the XTR200 is mistakenly connected to the power supply, and the VSP pin is grounded, the on-chip ESD diode between these pins is forward biased. The forward bias causes a large current to flow and damage the IC. Figure 7-2 shows the addition of a miswiring protection diode in series with the XTR200 power supply. This diode prevents reverse current from flowing out of the VSP pin through the ESD diode. The supply bypass capacitor, CBYP, placed at the VSP pin provides a low-impedance pathway to ground for high-frequency ESD events that forward bias the on-chip ESD diode. Include the forward voltage drop of the miswiring protection diode when calculating the minimum supply voltage to provide the necessary headroom for the XTR200. ESD Diode ESD Diode RLOAD Miswiring Protection Diode VSP GND OUT XTR200 CBYP VSupply Figure 7-2. Basic Miswiring Protection Diode in Series with Supply Figure 7-3 shows a basic reverse polarity protection circuit to protect the XTR200 in the event the ground voltage exceeds the supply or load voltage. In normal operation, the NMOS transistor is turned on via resistors R1 and R2. Select resistor values which produce an appropriate gate voltage for the NMOS from the range of expected power supply voltages. Zener diode ZD1 protects the NMOS gate from over-voltage. If V Supply is low but the voltage at the ground is high (reverse polarity condition) the NMOS is turned off, preventing current flow through the on-chip ESD diodes. Select an NMOS transistor with low RDS(ON) to minimize ground potential differences. Miswiring Protection DiodeCBYP VSupply NMOSZD1 ESD Diode ESD Diode VSP GND OUT XTR200 Figure 7-3. Basic Reverse Polarity Protection Figure 7-3 does not protect the XTR200 in the case that the ground connection is shorted to the power supply but the load is still grounded.

7.1.3 Power Dissipation in Current Output Mode

In current-output mode, the combination of low load resistances and relatively high output currents causes increased power dissipation in the XTR200 when using the internal output transistor. Equation 7 calculates the power dissipated in the XTR200. P D = V SP I Q + V SP − I O R SE T I O 10 + V SP − I O R L I O (7) Where:

  • VSP: Supply voltage in volts
  • IQ: Quiescent power supply current in amps (typically 325μA)
  • IO: Output current in amps
  • RSET: SET resistor value in ohms
  • RL: Load resistor value in ohms Equation 7 has three terms. The first term represents the operating dissipation of the XTR200 internal circuitry and is a function of the power supply voltage and the quiescent power supply current. The second term represents the power dissipated in the SET pathway of the XTR200 and is a function of the supply voltage, the SET current (1/10th the output current) and the SET resistor, RSET. The last, and most significant, term of the equation represents the power dissipation in the output circuitry of the XTR200 and is a function of the supply voltage, output current, and load resistance. Use the calculated power dissipation with the method Estimating Junction Temperature shows to estimate the XTR200 junction temperature for a given use case. Figure 7-6 shows the power dissipation of an XTR200 in current output mode using the internal transistor, a 24V supply, and a 1.33k Ω R SET for various load resistances. Power dissipation in the XTR200 is highest for low resistance loads and high output currents. Power dissipation decreases once the load voltage exceeds the voltage drop across the output circuitry of the XTR200, as seen in the 500 Ω load case above 26mA of output current.

7.1.4 Estimating Junction Temperature

The JEDEC standard now recommends using psi ( Ψ) thermal metrics to estimate the junction temperatures of the device when in-circuit on a typical PCB board application. These metrics are not thermal resistance parameters and instead offer a practical and relative way to estimate junction temperature. These psi metrics are determined as significantly independent of the copper area available for heat-spreading. XTR200 SBOSAL6A – JUNE 2025 – REVISED SEPTEMBER 2025 www.ti.com

The Thermal Information table lists the primary thermal metrics, which are the junction-to-top characterization parameter (ψJT) and junction-to-board characterization parameter (ψJB). These parameters provide two methods for calculating the junction temperature (T J), as described in the following equations. Use the junction-to-top characterization parameter ( ψJT) with the temperature at the center-top of device package (T T) to calculate the junction temperature. Use the junction-to-board characterization parameter ( ψJB) with the PCB surface temperature 1mm from the device package (TB) to calculate the junction temperature. T J = T T + Ψ JT × P D (8) where

  • PD is the dissipated power
  • TT is the temperature at the center-top of the device package T J = T B + Ψ JB × P D (9) where
  • TB is the PCB surface temperature measured 1mm from the device package and centered on the package edge For detailed information on the thermal metrics and how to use them, see the Semiconductor and IC Package Thermal Metrics application note. www.ti.com XTR200 SBOSAL6A – JUNE 2025 – REVISED SEPTEMBER 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 23 Product Folder Links: XTR200

7.2 Typical Applications

7.2.1 Analog Output Circuit for Field Transmitters

The XTR200 is designed as a fully-integrated output driver for field transmitters that transmit analog information in standard industrial ranges of 0mA to 20mA, 4mA to 20mA, and 0V to 10V. Figure 7-7 shows a simplified schematic of the output circuitry of a field transmitter. A digital-to-analog converter (DAC) provides the input signal to the XTR200 while a microcontroller controls the MODE and Output Disable (OD) pins and monitors the error flag pin. The XTR200 can run directly from the loop supply, which is specified for a range of 18V to 36V. The device is configured to use the internal output transistor to drive the load by shorting the IS and VG pins together.

7.2.1.1 Design Requirements

The design requirements for this application are listed in Table 7-1. These are chosen to closely represent the design requirements of industrial field transmitters. Although the standard ranges for transmitting information are 0mA to 20mA, 4mA to 20mA, and 0V to 10V, currents above 20mA and voltages above 10V are often used to indicate error conditions. This is why the design requirements specify output currents up to 22mA and output voltages up to 11.25V. Table 7-1.

7.2.1.2 Detailed Design Procedure

The only calculation required to complete the circuit design is a single external component, R SET. Resistor RSET determines the voltage-to-current transfer function of the circuit. The value of R SET is calculated using the maximum input voltage and the maximum output current as shown in Equation 10. R SET = 10 × V IN M AX I OUT M AX = 10 × 3V 22 mA = 1363.64 Ω 1.33 k Ω (10) A value of 1.33k Ω is chosen for R SET as this is a standard 1% resistor value that is very close to the calculated value of 1363.64 Ω and can still provide the required maximum output current of 22mA. Select a resistor with a low temperature coefficient and tight value tolerance to minimize the error introduced by this external component. No calculations are required to set the output voltage transfer function. The XTR200 has a fixed gain of 3.75V/V in voltage-output mode which is sufficient for a variety of DAC output voltage ranges. Consider the headroom requirement of the XTR200 when evaluating the load resistance and power supply voltage ranges. The worst case scenario is a minimum supply voltage of 18V and the maximum output current (22mA) into the maximum load resistor (500 Ω). In this case, the load voltage is 11V and the headroom (the difference between supply voltage and load voltage) is 7V. This case is well above the 2.5V headroom requirement of the XTR200 and sufficient for proper operation. The required maximum power supply voltage, 36V, is well within the limits recommended in Power Supply Recommendations when using the internal transistor. Figure 7-7 also shows a 0.1 μF bypass capacitor, C BYP, on the power supply pin, VSP, of the XTR200. The bypass capacitor location is a good design practice and helps provide a low-impedance supply for the XTR200 and filter out any residual noise on the power supply.

7.2.1.3 Application Curves

Figure 7-8 and Figure 7-9 show the output current and voltage transfer functions of the circuit. The calculated value of R SET, 1.33kΩ, gives a maximum output current of 22.56mA for an input voltage of 3V. The maximum output voltage is 11.25V for an input voltage of 3V.

7.2.2 Additional Applications

The XTR200 is useful in a variety of applications beyond voltage and current transmission. The wide supply and output current ranges, high output impedance, and excellent integration make the device well suited for sensor excitation as well as current monitoring in server power supply applications. Current Sources for RTD Measurements Resistance temperature detectors, or RTDs, are sensors which measure temperature through a change in resistance. RTDs are typically biased using a constant current source and then the temperature-dependent voltage across the sensor can be measured. Figure 7-10 illustrates a 2-wire ratiometric RTD measurement system employing the XTR200 as a current source. The excitation current produced by the XTR200, I EXC, flows through the RTD as well as a reference resistor, RREF, which produces the reference voltage for the ADC.

Current Monitor (Imon) Output for Modular Hardware System-Common Redundant Power Supplies (M- CRPS) The M-CRPS specification requires that server power supplies have a current monitor (Imon) output for the 12V bus. The Imon output produces a scaled down replica of the current flowing on the 12V bus with a ratio of either 10μA/A or 0-2mA indicating 0-200% of rated output current. Figure 7-14 shows an example implementation of the Imon function using an INA241A5 current shunt monitor amplifier and an XTR200. The INA241A5 outputs a voltage of 0V to 2V, corresponding to 0-100A flowing through the 100 μΩ shunt resistor.

If the gate of the NMOS is low, the XTR200 outputs 10 μA per Amp of current flowing on the 12V bus. If the gate of the NMOS is high, then the 2, 20k Ω resistors are connected in parallel and the transfer function is 0-2mA corresponding to 0-200% of rated output current. Diode D1 and op amp U3 form a clamping circuit which clamps the output voltage to 3.3V when the voltage drop across diode D2 is accounted for. Diode D2 prevents reverse current flow in systems with multiple Imon signals connected in parallel. D2 must be a low-leakage diode to meet the requirement of <500nA leakage at 85°C. Q1, Q2, R2, and R3 implement "presence" functionality required for backwards compatibility with older power supplies. The standards document suggests a low-leakage PJFET for Q1, such as the MMBFJ177L. XTR200 SBOSAL6A – JUNE 2025 – REVISED SEPTEMBER 2025 www.ti.com

7.3 Power Supply Recommendations

The XTR200 operates over a supply voltage range of 8V to 60V. However, consider the environmental temperature, load current, and load resistance in the overall system design. Figure 7-15 shows the thermally- limited maximum supply voltage of the XTR200 over a range of PCB temperatures. Figure 7-15 shows a worst-case scenario of 22mA output current into a 0 Ω load using the internal output transistor, IS and VG pins shorted. The black curve shows the supply voltage resulting in a 125°C junction temperature (the maximum specified temperature of the XTR200) for the given PCB temperature. The red curve shows the supply voltages resulting in a 150°C junction temperature (maximum operating temperature of the XTR200) for a given PCB temperature. At approximately 150°C, the Error Flag pin (EF) voltage goes low, warning of high junction temperature. The XTR200 thermal shutdown circuitry disables the output for junction temperatures above 160°C. When the junction temperature falls back below 150°C, the output is re-enabled. For PCB temperatures below 70°C, the maximum recommended supply voltage is limited by the voltage rating of the XTR200 internal circuitry rather than thermal considerations. If high-temperature and high-supply-voltage operation is required, use an external transistor to deliver the load current as described in Using an External Transistor.

Maximum Recommended Supply Voltage vs PCB Temperature (Internal Output Transistor) Consider the headroom specification of the XTR200 when determining the working power supply range of a system. The term headroom defines the difference between the supply voltage of the XTR200 and the load voltage as shown in Figure 7-16 . Above the minimum supply voltage, 8V, confirm that the XTR200 supply voltage is at least 2.5V above the load voltage.

7.4 Layout

7.4.1 Layout Guidelines

Figure 7-17 shows an example layout for the XTR200. For particular requirements of an application or PCB assembly process, refine the layout. To maximize the performance of the device:

  • Place the RSET resistor as close as possible to the SET and GND pins to minimize trace resistance in series with the RSET resistor.
  • When using the integrated output transistor, short the IS and VG pins together as close as possible to the device. This reduces trace resistance to maximize output headroom and prevent noise coupling into the output signal.
  • Place power supply bypass capacitors near the power supply pin, between the device and any vias used for the supply connection. Provide a low impedance connection to ground for bypass capacitors.
  • Connect the thermal pad to a ground plane or pour and, if possible, extend the ground pour beyond the device to maximize power dissipation. Soldering the exposed pad significantly improves board-level reliability during temperature cycling, key push, package shear, and similar board-level tests. Even with applications that have low power dissipation, solder the exposed pad to the PCB to provide structural integrity and long-term reliability. Physical dimensions for the package and pad are shown in Mechanical, Packaging, and Orderable Information.

7.4.2 Layout Example

close to VSP pin to minimize impedance to ground Place RSET resistor close to SET and GND pins to minimize parasitic impedances When using integrated output transistor, connect VG and IS pins directly at the IC Connect the thermal pad to a large ground plane to improve power dissipation Figure 7-17.
