PT6504

PT6500 Series 8 Amp 5V/3.3V Input Adjustable ISR with 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-Temperature Protection 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.
