It is also the V dc GND I/O reference for the Inhibit and V O Adjust control inputs. V I I The positive input voltage power node to the module, which is referenced to common GND. The Inhibit pin is an open-collector/drain active-low input that is referenced to GND. Applying a low-level ground signal to this input disables the module s output and turns off the output voltage. When the Inhibit I Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left open-circuit, the module will produce an output whenever a valid input source is applied. A resistor must be connected between this pin and GND (pin to set the output voltage. If left open-circuit, the output voltage defaults to its minimum adjust value. The temperature stability of the V O Adjust O resistor should be 100 ppm/ C (or better). The PTN78000W set-point range is 2.5 V to 12.6 The PTN78000H set-point range is 11.85 V to The standard resistor value for a number of common output voltages is provided in the application information.

The adjustment range is from 2.5 V to 12.6 V for PTN78000W. The adjustment range is from 11.85 V to V for PTN78000H. If pin is left open, the output voltage defaults to the lowest value. Table gives the preferred value of the external resistor for several standard voltages, with the actual output voltage that the value provides. For other output voltages, the value of the required resistor can be calculated using Equation and the constants for the applicable product in Table Alternatilvey, R SET can be simply selected from the range of values given in Table Figure shows the placement of the required resistor. Table R SET Formula Constants PRODUCT V MIN (V) R P Ω PTN780x0W 2.5 6.49 PTN780x0H 11.824 6.65 The PTN78000 is a step-down switching regulator. In order that the output remains in regulation, the input voltage must exceed the output by a minimum differential voltage. (Please refer to the input voltage range requirements in the electrical characteristics table.) Another consideration is the pulse width modulation (PWM) range of the regulator's internal control circuit. For stable operation, its operating duty cycle should not be lower than some minimum percentage. This defines the maximum advisable ratio between the regulator input and output voltage magnitudes. As an example, for satisfactory performance, the operating input voltage range of the PTN78000x must adhere to the following requirements. For PTN78000W output voltages lower than the minimum input voltage is O V or whichever is higher. For PTN78000W output voltages equal to V and higher, the minimum input voltage is O 2.5 V For PTN78000W, the maximum input voltage is (10 x V O or whichever is less. For PTN78000H output voltages lower than the minimum input voltage is O V or whichever is higher.

www.ti.com ADJUST POWER MODULES The minimum requirement for the input of PTN78000W is 2.2 µ F of ceramic capacitance. The dielectric may be either an X5R or X7R temperature characteristic. Ceramic capacitors should be located within 0.5 inch (1,27 cm) of the regulator input pins. Electrolytic capacitors can be used at the input, but only in addition to the required ceramic capacitance. The minimum ripple current rating for any nonceramic capacitance must be at least 650 mArms. The ripple current rating of electrolytic capacitors is a major consideration when they are used at the input. This ripple current requirement can be reduced by placing more ceramic capacitors at the input, in addition to the minimum required capacitance. Tantalum capacitors are not recommended for use at the input bus, as none were found to meet the minimum voltage rating of x (maximum dc voltage ac ripple). The rating is standard practice for regular tantalum capacitors to ensure reliability. Polymer-tantalum capacitors are more reliable and are available with a maximum rating of typically These can be used with input voltages up to The minimum requirement for the input of PTN78000H is 4.7 µ F of ceramic capacitance. The dielectric may be either an X5R or X7R temperature characteristic. Ceramic capacitors should be located within 0.5 inch (1,27 cm) of the regulator input pins. Electrolytic capacitors can be used at the input, but only in addition to the required ceramic capacitance. The minimum ripple current rating for any nonceramic capacitance must be at least 350 mArms. The ripple current rating of electrolytic capacitors is a major consideration when they are used at the input. This ripple current requirement can be reduced by placing more ceramic capacitors at the input, in addition to the minimum required capacitance. Tantalum capacitors are not recommended for use at the input bus, as none were found to meet the minimum voltage rating of x (maximum dc voltage ac ripple). The rating is standard practice for regular tantalum capacitors to ensure reliability. Polymer-tantalum capacitors are more reliable and are available with a maximum rating of typically These can be used with input voltages up to The minimum capacitance required to insure stability is a 100 µ Either ceramic or electrolytic-type capacitors can be used. The minimum ripple current rating for the nonceramic capacitance must be at least 150 mA rms. The stability of the module and voltage tolerances will be compromised if the capacitor is not placed near the output bus pins. A high-quality, computer-grade electrolytic capacitor should be adequate. A ceramic capacitor can be also be located within 0.5 inch (1,27 cm) of the output pin. For (sudden changes in load current), the regulator response improves with additional capacitance. Additional electrolytic capacitors should be located close to the load circuit. These capacitors provide decoupling over the frequency range, kHz to 150 kHz. Aluminum electrolytic capacitors are suitable for ambient temperatures above For operation below tantalum or OS-CON type capacitors are recommended. When using one or more nonceramic capacitors, the calculated equivalent ESR should be no lower than m Ω (17 m Ω using the manufacturer's maximum ESR for a single capacitor). A list of capacitors and vendors are identified in Table and Table the recommended capacitor tables. Above 150 kHz the performance of aluminum electrolytic capacitors becomes less effective. To further reduce the reflected input ripple current, or the output transient response, multilayer ceramic capacitors must be added. Ceramic capacitors have low ESR and their resonant frequency is higher than the bandwidth of the regulator. When placed at the output, their combined ESR is not critical as long as the total value of ceramic capacitance does not exceed 200 µ Submit Documentation Feedback Copyright 2004 2008, Texas Instruments Incorporated Product Folder Link(s): PTN78000W PTN78000H

www.ti.com SLTS230C NOVEMBER 2004 REVISED SEPTEMBER 2008 Tantalum type capacitors may be used at the output, and are recommended for TPS, Sprague 593D/594/595, and Kemet T495/T510/T520 capacitors series are suggested over many other tantalum types due to their rated surge, power dissipation, and ripple current capability. As a caution, many general-purpose tantalum capacitors have considerably higher ESR, reduced power dissipation, and lower ripple current capability. These capacitors are also less reliable as they have lower power dissipation and surge current ratings. Tantalum capacitors that do not have a stated ESR or surge current rating are not recommended for power applications. When specifying OS-CON and polymer tantalum capacitors for the output, the minimum ESR limit is encountered well before the maximum capacitance value is reached. The capacitor table, Table and Table identifies the characteristics of capacitors from various vendors with acceptable ESR and ripple current (rms) ratings. The recommended number of capacitors required at both the input and output buses is identified for each capacitor type. This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The rms rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life. The transient response of the dc/dc converter has been characterized using a load transient with a di/dt of µ The typical voltage deviation for this load transient is given in the data sheet specification table using the required value of output capacitance. As the di/dt of a transient is increased, the response of a converter's regulation circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation of any dc/dc converter once the speed of the transient exceeds its bandwidth capability. If the target application specifies a higher di/dt or lower voltage deviation, the requirement can only be met with additional output capacitor decoupling. In these cases, special attention must be paid to the type, value, and ESR of the capacitors selected. If the transient performance requirements exceed those specified in the data sheet, the selection of output capacitors becomes more important. Review the minimum ESR in the characteristic data sheet for details on the capacitance maximum.

During power up, internal soft-start circuitry slows the rate that the output voltage rises, thereby limiting the amount of in-rush current that can be drawn from the input source. The soft-start circuitry introduces a short time delay (typically ms ms) into the power-up characteristic. This is from the point that a valid input source is recognized. Figure shows the power-up waveforms for a PTN78000W, operating from a 12-V input and with the output voltage adjusted to The waveforms were measured with a 1.5-A resistive load. Figure 28. Power-Up Waveforms The undervoltage lockout (UVLO) circuit prevents the module from attempting to power up until the input voltage is above the UVLO threshold. This prevents the module from drawing excessive current from the input source at power up. Below the UVLO threshold, the module is held off. The PTN78000 modules protect against load faults with a continuous current limit characteristic. Under a load fault condition, the output current cannot exceed the current limit value. Attempting to draw current that exceeds the current limit value causes the module to progressively reduce its output voltage. Current is continuously supplied to the fault until it is removed. On removal of the fault, the output voltage promptly recovers. When limiting output current, the regulator experiences higher power dissipation, which increases its temperature. If the temperature increase is excessive, the module's overtemperature protection begins to periodically turn the output voltage completely off. A thermal shutdown mechanism protects the module's internal circuitry against excessively high temperatures. A rise in temperature may be the result of a drop in airflow, a high ambient temperature, or a sustained current-limit condition. If the junction temperature of the internal control IC rises excessively, the module turns off, reducing the output voltage to zero. The module instantly restarts when the sensed temperature decreases by a few degrees. Note: Overtemperature protection is a last resort mechanism to prevent damage to the module. It should not be relied on as permanent protection against thermal stress. Always operate the module within its temperature derated limits, for the worst-case operating conditions of output current, ambient temperature, and airflow. Operating the module above these limits, albeit below the thermal shutdown temperature, reduces the long-term reliability of the module.

Figure shows the the circuit used to demonstrate the inhibit function. Note the discrete transistor (Q1). Turning on applies a low voltage to the Inhibit control pin and turns the module off.

However, some ripple/noise. This application note describes various filters and design techniques found to be successful in reducing both input and output ripple/noise. The easiest way to reduce output ripple and noise is to add one or more µ F ceramic capacitors, such as shown in Figure Ceramic capacitors should be placed close to the output power terminals. A single µ F capacitor reduces the output ripple/noise by 10% to 30% for modules with a rated output current of less than (Note: is recommended to improve the regulators transient response and does not reduce output ripple and noise.) Switching regulators draw current from the input line in pulses at their operating frequency. The amount of reflected (input) ripple/noise generated is directly proportional to the equivalent source impedance of the power source including the impedance of any input lines. The addition of C1, minimum µ F ceramic capacitor, near the input power pins, reduces reflected conducted ripple/noise by 30% to 50%. Figure 31. Adding High-Frequency Bypass Capacitors To The Input and Output If a further reduction in ripple/noise level is required for an application, higher order filters must be used. A π (pi) filter, employing a ferrite bead (Fair-Rite part number 2673000701 or equivalent) in series with the input or output terminals of the regulator reduces the ripple/noise by at least db (see Figure and Figure In order for the inductor to be effective in reduction of ripple and noise ceramic capacitors are required. (Note: see Capacitor Recommendations for the PTN78000W for addtional information on vendors and component suggestions.) These inductors plus ceramic capacitors form an excellent filter because of the rejection at the switching frequency (650 kHz MHz). The placement of this filter is critical. It must be located as close as possible to the input or output pins to be efffective. The ferrite bead is small (12,5 mm x mm), easy to use, low cost, and has low dc resistance. Fair-Rite also manufactures a surface-mount bead (part number 2773021447), through hole (part number 2673000701) rated to but in this application, it is effective to A on the output bus. Inductors in the range of µ H to µ H can be used in place of the ferrite inductor bead.
