Product Selector Guide  
8 AMP ADJUSTABLE ISR  
WITH SHORT-CIRCUIT PROTECTION  
• 8A Single Device Power  
• Up to 90% efficiency (PT6501)  
• Small SIP Footprint  
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.  
• Standby Function  
• Internal Short Circuit Protection  
• Over-Temperature Protection  
• Adjustable Output Voltage  
The PT6500 series is Power Trends’  
new high performance +3.1 to 6V  
input, 8 Amp, 14-Pin SIP (Single In-  
line-Package) Integrated Switching  
Regulator (ISR). This high-perfor-
