Description

The PT6510 series of power modules is the recommended direct replacement for the PT6500 series in existing designs. The modules have the same output cur- rent rating as the PT6500 series (8 A) and were designed to be functionally iden- tical in as many aspects as possible. This includes the input voltage range, on/off standby control, and output voltage ad- justment. When used as a replacement, a PT6510 series part exhibits a number of perfor- mance enhancements over its PT6500 series equivalent. These include improved power dissipation and efficiency, signifi- cantly reduced inrush current, and better line and load regulation. The modules are housed in the same 14-Pin SIP (Single In-line Package), and include the same package options.

For technical support or further information, visit http://power.ti.com PT6510 Series Using the PT6510 Series as a Replacement for the PT6500 Series in Existing Designs Scope The PT6510 series of power modules is the recommended plug-in replacement for PT6500 series parts. The PT6510 series uses the same single-in-line package (SIP) outlines and footprint as the PT6500 series, and was designed to be functionally identical to the PT6500. This application note highlights the differences in electrical performance between a PT6510 series replacement compared to an original PT6500 series part. Overview The features that the PT6510 series share with the PT6500 series includes the output current rating, thermal shutdown, and on/off standby. The input voltage range, output voltage adjustment, and output voltage options are also the same. In addition, applications that use the PT6510 series as a replacement will experience a number of performance enhancements. These include improved efficiency and power dissipation, lower in-rush current and output ripple voltage. The ‘off’ standby current is also significantly reduced. Table 1-1 provides a cross reference between the current PT6500 series part num- bers and their equivalent PT6510 series part. Table 1-1; PT6500 / PT6510 Series Equivalent Parts PT6500 Series V OUT PT6510 Series PT6501 3.3 V PT6511 PT6502 1.5 V PT6512 PT6503 2.5 V PT6513 PT6504 3.6 V PT6514 PT6505 1.2 V PT6515 PT6506 1.8 V PT6516 Electrical and Functional Differences Although the PT6510 series was designed as a drop-in replacement for PT6500 series, there are minor differences in the electrical characteristics. These are described in the following text and should be used to assess the replace- ment part’s compatibility with the system or end product. A replacement part’s compatibility with the system can be further verified with appropriate board-level tests. On/Off Standby: The Standby input of the PT6510 series is compatible with both the logic polarity and thresholds of PT6500 series. One exception is the internal pull-up voltage, which is slightly higher on the PT6510 parts. The open-circuit voltage for the PT6510 series is the input voltage, V in, versus about 1 V for the PT6500 series. This should not be a problem if the standby input is controlled with an open-drain transistor with a sufficient max-Vds rating. Over-Current & Over -Temperature Protection: To protect against short circuits and load impedance faults, the PT6500 em ploys a constant output current limit combined with over-temperature shutdown. The PT6500 will feed a limited steady-state current into a load fault. When limiting output current, the PT6500 exhibits higher power dissipation, which increases the module's operating temperature. When its internal tem- perature rises above the over-temperature threshold, the module will shut itself down for a few seconds. The module will then continue to periodically shut down until the load fault is removed. The over-current protection mechanism of the PT6510 series is different. If the output current increases above the modules over-current thr eshold, its output voltage is momentarily turned off. It t hen attempts to recover by executing a soft-start power up. The module will continue in a rapid succession of shutdowns and restarts until the load fault is removed. During this period the output current is not steady state, but a series of short high-amplitude pulses (frequency < 100 Hz). However, when operating into a short-circuit load fault, the average output current and power dissipation are significantly lower than under normal operation. Power-Up Characteristic: Following the application of a valid input source, the PT6510 series modules exhibit a slightly longer time delay than the equivalent PT6500 series part. The PT6510 series has a soft-start power-up feature, which l owers the in-rush current at its input. Figure 1-1 and Figure 1-2 show the power-up charac- teristics of the PT6501 and PT6511 respectively. Both modules have a 3.3-V regulated output, and rise to their regulated output voltage in a similar period. Note that the output voltage of the PT6501 begins to rise when the input voltage reaches 2.2 V, whereas the output voltage of the PT6511 doesn’t begin to rise until the input voltage has reached 3.5 V.

The ripple current rating and ESR does not meet the requirements. Capacitor Recommendations for the PT6510 Series of Integrated Switching Regulators Input Capacitors: The recommended input capacitance is determined by 330 µF minimum value (300 µF for Oscon or low-ESR tantalum types), and 1 A minimum ripple current rating. Ripple current and less than 100 m Ω equivalent series resistance (ESR) are the major parameters, along with temperature, when selecting an input capacitor. Tanta- lum capacitors have a recommended minimum voltage rating of twice 2 × (max. DC voltage + AC ripple). This is standard practice to insure reliability. Output Capacitors: The ESR of the required output capacitor must not be greater than 150 m Ω . Electrolytic capacitors have poor ripple performance at frequencies greater than 400 kHz but excellent low-frequency transient response. Above the ripple frequency, ceramic capacitors are necessary to improve the transient response and reduce any high frequency noise components apparent during higher current excursions. Preferred low-ESR type capacitor part numbers are identified in Table 2-1. Tantalum Capacitors Tantalum type capacitors may be used for the output but only the AVX TPS, Sprague 593D/594/595, or Kemet T495/T510 series. These capacitors are recommended over many other tantalum types due to their higher rated surge, power dissipation, and rip ple current capability. As a caution the TAJ series by AVX is not recommended. This series has considerably higher ESR, reduced power dissipation, and lower ripple current capability. The TAJ series is less reliable than the AVX TPS series when determining power dissipation capability. Tantalum or Oscon types are recommended for applications where ambient temperatures fall below 0 °C. Capacitor Table Table 2-1 identifies the characteristics of capacitors from a number of vendors with acceptable ESR and ripple current (rms) ratings. The 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 ripple current rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life. roticapaC /rodneV tnenopmoC seireS scitsiretcarahCroticapaCy titnauQ gnikroW egatloV) Fµ(eulaV RSE.xaM zHk001ta elppiR.xaM C°58tatnerruC )smrI( eziSlacisyhP )mm( tupnI suB tuptuO suB rebmuNrodneV cinosanaP CF V52 V53 V53 Fµ065 Fµ093 Fµ033 5600.0 Ω 560.0 Ω 711.0 Ω Am5021 Am5021 Am555 51x5.21 51x5.21 5.11x8 R/N S165E1CFUEE S193V1CFUEE 133C1CFUEE detinU noC-imehC /SF/VXL ZXL V61 V53 V01 V02 Fµ033 Fµ074 Fµ033 Fµ051 021.0 Ω 250.0 Ω 520.0 Ω 030.0 ÷2 Ω Am555 Am0221 Am0053 Am0023 21x8 02x01 5.01x01 5.01x01 R/N LL21X8M133BV61ZXL LL02X01M174BV53ZXL M033SF01 M051SF02 nocihciN MP/LP V53 V53 V05 065F µ 033F µ 074F µ 840.0 Ω 560.0 ÷2 Ω 640.0 Ω Am0631 Am0201 Am0741 51x61 51x5.21 51x81 6HHM165V1LPU 6HHM133V1LPU 6HHM1174H1MPU cinosanaP CF )gtMecafruS( V01 V53 V61 0001F µ 033F µ 033F µ 340.0 Ω 560.0 Ω 051.0 Ω Am5021 Am5021 Am076 5.61x21 61x5.21 2.01x01 R/N QL201A1CFVEE QL133V1CFVEE P133C1CFVEE SS-nocsO VS V01 V01 V02 033F µ Fµ033 051F µ 520.0 Ω 520.0 Ω 420.0 ÷2 Ω Am0053> Am0083> Am0063 5.01x0.01 3.01x3.01 3.01x3.01 M033SS01 M033VS01 M051VS02 tnuoMecafruS=VS XVA mulatnaT SPT V01 V01 V01 Fµ033 Fµ033 Fµ022 001.0 ÷2 Ω 001.0 ÷2 Ω 590.0 Ω Am0052> Am0003> Am0002> xL3.7 xW3.4 H1.4 0010R010M733VSPT 0600R010M733VSPT 0010R5010M722VSPT temeK /015T 594T V01 V01 Fµ033 Fµ022 330.0 Ω 70.0 ÷Ω 530.0=2 Ω Am0041 Am0002> W7.5xL3.7 H0.4x SA010M733X015T SA010M722X594T eugarpS D495 V01 V01 Fµ033 Fµ022 540.0 Ω 560.0 Ω Am0532 Am0002> xL3.7 xW0.6 H1.4 T2R0100X733D4 T2D0100X722D495 PT6510 Series

For technical support and further information, visit http://power.ti.com PT6510 Series Using the Standby Function of the PT6510 Series of Integrated Switching Regulators The PT6510 series of power modules incorporate a Standby function. This may be used in applications that require power-up/shutdown sequencing, and wherever there is a requirement for the output status of the mod- ule to be controlled by external circuitry. The standby function is provided by the STBY* control, pin 3. If pin 3 is left open-circuit 1 the regulator operates normally, and provides a r egulated output whenever a valid supply voltage is present at applied to V in (pins 4-6) with respect to GND (pins 7–10). Applying a ground signal to pin 3 disables the regulator’s output and reduces the input current to about 1 mA 4. The standby control may also be used to hold off the regulator output during the period that input power is applied. Pin 3 is ideally controlled with an open-drain discrete transistor 1 (See Figure 3-1). It may also be driven directly from a dedicated TTL 3 compatible gate. Table 3-1 gives the circuit parameters for the control of this input. Table 3-1 Standby Control Requirements (2) Parameter Min Typ Max Input Low (VIL) –0.1 V 0.4 V Input High (VIH) 2 V V in Input Low Current (I IL) –0.4 mA Notes:

1 The standby control input is i deally controlled using an

open-drain discrete transistor. An external pull-up resistor is not necessary. The open-circuit voltage of the STBY* pin is the input voltage, V in. 2. To ensure the regulator output is disabled, the control pin must be pulled to less than 0.4 Vdc with a low-level 0.5-mA sink to ground. 3. The STBY* input is also compatible with a differential output from standard TTL logic, providing the IC shares the same supply voltage as the module. 4. When the regulator output is disabled the current drawn from the input source is typically reduced to about 1 mA. Figure 3-1 Turn-On Time: In the circuit of Figure 3-1, turning Q 1 on applies a low voltage to the STBY control (pin 3) and disables the regulator ouput. Corr espondingly, turning Q1 off removes the low-voltage signal and enables the output. Once enabled, the output will typically experience a 10–15 ms delay followed by a predictable ramp-up of voltage. The regulator should provide a fully regulated output voltage within 40 ms. The waveform of Figure 3-2 shows the output voltage and input current waveforms of a PT6511 (3.3 V) following the turn-off of Q1. The turn off of Q1 corresponds to the rise in Vstby. The waveforms were measured with a 5 Vdc input voltage, and 4.5 A resistive load.

T able 4-1 gives the allowable adjust- ment range for each model in the series as V a (min) and Va (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor R 2, between Vo Adjust (pin 14) and GND (pins 7-10). Adjust Down: Add a resistor (R1), between Vo Adjust (pin 14) and Vout (pins 11-13). Refer to Figure 4-1 and Table 4-2 for both the placement and value of the required resistor, either (R1) or R2 as appropriate. Notes: 1. Use only a single 1 % resistor in either the (R1) or R2 location. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from Vo Adjust to either GND, Vout, or the Vo Sense pin. Any capacitance added to the Vo Adjust pin will affect the stability of the ISR. 3. If the remote sense feature is used, connecting the resistor (R1) between Vo Adjust (pin 14) and Vo Sense (pin 1) can benefit load regulation. 4. The minimum input voltage required by the part is Vout + 1.2 or Vin(min) from Table 4-1, whichever is higher. Figure 4-1 The values of (R1) [adjust down], and R 2 [adjust up], can also be calculated using the following formulae.
