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  
grated Switching Regulator (ISR).  
This ISR allows the 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 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.  
Standby Function  
Internal Short Circuit Protection  
Over-Temperature Protection  
Adjustable Output Voltage  
The PT6500 series is a high perfor-  
mance +3.1 to 6V input, 8 Amp, 14-Pin
