Description

The PT6880 product family is a series of highly efficient, non-isolated integrated switching regulator (ISR) modules. De- signed to operate off a wide-input bus, these regulators produce a tightly reg- ulated output voltage at load currents of up to 5A. The series includes standard output voltage options ranging from 2.5V to 15V. The series is an ideal choice for general purpose and industrial applications that operate off a 24/28V battery providing a low-cost alternative to a fully isolated converter. The PT6880 series is packaged in a thermally efficient, 18-pin, space-saving copper case. Both vertical and horizontal configurations are available, including surface-mount.

(2) The stated maximum input voltage assumes the nominal output voltage. If the output voltage is adjusted (trimmed) to some oth er value, consult the related application note on output voltage adjustment for the revised input voltage limitations. (3) The STBY* control (pin 4) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit voltage is low (less than 5V). Consult the related application note for interface considerations. (4) For guidance on suitable input and output capacitors consult the accompanying application note, “Capacitor Recommendations f or the PT6880 Series.” (5) See Safe Operating Area curves or contact the factory for the appropriate derating. (6) During solder reflow of SMD package version do not elevate the module case, pins, or internal component temperatures above a peak of 215°C. For further guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Mount Products,” (SLTA 051). (7) The case pins on through-hole package types (suffixes N & A) must be soldered. For more information consult the applicable p ackage outline drawing.

For technical support and more information, see inside back cover or visit www.ti.com PT6880 Series Table 1-1: Input/Output Capacitors Notes: (1) N/R –Not recommended. The voltage rating does not meet the minimum operating limits. (2) A fused input bus is recommended when tantalum capacitors are used on the output bus. Capacitor Recommendations for the PT6880 Regulator Series Input Capacitor: The required input capacitor is determined by a 1.2Arms minimum ripple current rating and 560µF capacitance value. The ripple current rating and <120mΩ equivalent series resistance (ESR) are the major considerations, along with temperature, when designing with different types of capacitors. Tantalum/Os-Con® capacitors are not recommended due to a minimum voltage rating of 2 × (the maximum DC voltage + AC ripple). This is necessary to improve the reliability of these capacitors in high bus applications. Output Capacitors: The ESR specification of the output capacitor should be at least 50m Ω . Electrolytic capacitors have marginal ripple performance at frequencies greater than 400kHz 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. Electrolytic capacitors with appropriate ESR values are identified in Table 1-1. In low-temperature applications (<0°C), a higher capacitance with lower ESR will improve performance. Os-Con® and ultra low ESR type capacitors are not recom- mended on the output bus as they degrade regulator stability. Tantalum Capacitors (For V out <5.1V) Tantalum type capacitors can be used on the output bus for output voltages less than 5.1V. Voltages higher than this will exceed the capacitor’s published surge voltage limits. If tantalum capacitors are located on the output bus, an appropriate fuse with I 2t current derating is recommended along with an external clamp component. An Output Over-voltage Clamp (OOVC) will fault the output fuse protecting the capacitors in event of an over-voltage condi- tion. The OOVC can be a simple zener high power di- ode, 3-5W, located on the load side of the output bus. The zener diode should be rated to 1.3 times the normal out- put voltage. Capacitor Table Table 1-1 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 (Equivalent Series Resistance at 100kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life. /rodneVroticapaC seireS scitsiretcarahCroticapaCy titnauQ gnikroW egatloV )Fµ(eulaVt nelaviuqE)RSE( ecnatsiseRseireS mumixaMC°501 elppiR )smrI(tnerruC lacisyhP )mm(eziS tupnI suB tuptuO suB rebmuNtraProdneV cinosanaP )laidaR(CF )gtMecafruS(KF/CF V05 V05 V05 V36 V53 V05 065 093 093 086 033 0001 860.0 Ω 080.0 Ω 080.0 Ω 0800 Ω 080.0 Ω 370.0 Ω Am0091 Am0161 Am0161 Am0961 Am058 Am0161 81 × 51 51x61 61 × 51 81 × 5.61 01 × 2.01 61 × 5.61 R/N )1( 165H1CFUEE S193H1CFUEE S193H1CFUEE M186J1KFVEE P133V1KFVEE M201H1KFVEE noc-imehCdetinU seireSVXL/ZXL )gtMecafruS(YVM V05 V53 V53 086 033 022 840.0 Ω 860.0 Ω 051.0 Ω Am0481 Am0501 Am076 61 × 02 01 × 61 01 × 3.01 R/N )1( R/N )1( LL02X61M186BV05ZXL LL61X01M133BV53VXL PT01X01M1122CV53YVM nocihciN seireSMP V05 V36 V05 065 065 033 440.0 Ω 930.0 Ω 060.0 Ω Am0551 Am0041 Am0121 61 × 02 81 × 02 61 × 51 6HHM165H1MPU 6HHM165J1MPU 6HHM133H1MPU mulatnaTXVA )tgtMecafruS(SPT V01 V01 033 033 01.0 Ω 60.0 Ω Am0052> Am0003> L3.7 × W7.5 × H1.4 R/N )1( R/N )1( 0010R010M733ESPTV ( o )V1.5< 0600R010M733VSPTV ( o )V1.5< mulatnaTtemeK )2( seireS594T/694T (t nuoMecafruS) V01 V01 022 022 005.0 Ω 070.0 Ω Am005 Am0002> W3.4 × L3.7 × H0.4 R/N )1( R/N )1( SA010M722X694TV ( o )V1.5< SA0010M722X594TV ( o )V1.5< mulatnaTeugarpS )2( seireSD495 (t nuoMecafruS) V010 330 31.0 Ω Am3931L 2.7 × W6 × H1.4 R/N )1( 1T 2R0100X733D595V ( o )V1.5<

For technical support and more information, see inside back cover or visit www.ti.com PT6880 Series Adjusting the Output Voltage of the PT6880 5-A Excalibur™ Converter Series The output voltage of the Power Trends PT6880 Excalibur series of ISRs may be adjusted higher or lower than the factory trimmed pre-set voltage with the addition of a single external resistor 1. Table 3-1 gives the respective allowable adjustment 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 R2, between pin 1 (Vo Adjust) and pins 6, 7 /11-14 (GND). Adjust Down: Add a resistor (R1), between pin 1 (Vo Ad- just) and pins 15-17 (Vout). Refer to Figure 3-1 and Table 3-2 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 Remote Sense pin. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3. If the remote sense feature is being used, connecting the resistor (R1) between pin 1 (Vo Adjust) and pin 18 (Remote Sense) can benefit load regulation. 4. For output voltages above 10Vdc, the maximum output current must be limited to 4Adc. 5. Adjustments to the output voltage may place additional limits on the input voltage for the part. The revised limits must comply with the following requirements. V in (min) = (V out + 3)V or 15V, whichever is higher. Vin (max) = (10 x V out )V or 36V, whichever is less.
