Technical content

  • 8A Single Device Power
  • Up to 90% efficiency (PT6501)
  • Small SIP Footprint
  • Standby Function
  • Internal Short Circuit Protection
  • Over-T emperature Protection
  • Adjustable Output Voltage The PT6500 series is Power T rends’ new high performance +3.1 to 6V input, 8 Amp, 14-Pin SIP (Single In- line-Package) Integrated Switching Regulator (ISR). This high-perfor- mance ISR allows easy integration of high-speed, low-voltage Pentium pro- cessors and their support logic into existing 3.3V or 5V systems without redesigning the central power supply. The high-performance PT6502 solves the problem of providing the low ter- minating voltages required by BTL/ Futurebus+, CTT, HP , and GTL Buses from existing 3.3V or 5V power rails without redesigning the central power supply.

T able 1 accordingly gives the 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 14 (Vo adjust) and pins 7-10 (GND). Adjust Down: Add a resistor (R1), between pin 14 (Vo adjust) and pins 11-13 (Vout). Refer to Figure 1 and T able 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 loca- tion. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from V o 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 14 (Vo adjust) and pin 1 (Remote Sense) can benefit load regulation. 4. The minimum input voltage required by the part is Vout + 1.2 or 3.1V , whichever is higher.
