PT6500 Series
8 Amp 5V/3.3V Input Adjustable ISR w i t h Short-Circuit Protection
SLTS034A
(Revised 8/23/2000)
· · · · · · ·
8A Single Device Power Up to 90% efficiency (PT6501) Small SIP Footprint Standby Function Internal Short Circuit Protection Over-T mperature Protection e Adjustable Output Voltage
The PT6500 series is a high performance +3.1 to 6V input, 8 Amp, 14-Pin SIP (Single In-line-Package) Inte-
grated Switching Regulator (ISR). This ISR allows the integration of high-speed, low-voltage Pentium processors and their support logic into existing 3.3V or 5V systems without redesigning the central power supply. The PT6502 (1.5V) provides the low terminating voltages required by BTL/ Futurebus+, CTT, HP and GTL Buses , from existing 3.3V or 5V power rails.

(1) ISR will operate down to no load with reduced specifications. (2) The minimum input voltage required by the part is Vout +1.2V or 3.1V, whichever is greater. (3) For operation below 0°C, use tantalum capacitors. For more information see the related applicatoin note, "PT6000/7000 Series Capacitor Recommendations." (4) See Thermal Derating charts.
Input/Output Capacitors: The PT6500 series requires a 330µF electrolytic or tantalum input and output capacitor for proper operation in all applications. C 1 (input) must be rated for 1.2Arms and 100m max. ESR. C2 (output) must must be rated for 400mArms ripple current and 0.2 max. ESR.
