Description  
Ordering Information  
The PT7761 is a high performance  
integrated switching regulator (ISR),  
housed in a solderable, 31-pin space-  
saving copper package. Operating  
from and input voltage of +5V, the  
PT7761 provides up to 40A of low-  
voltage power for the industrys latest  
DSPs, and µ-Processors.  
mand high power supply currents at  
low output voltages.  
The PT7761 is programmable from  
1.3V to 3.5V via a 5-bit input, which  
is compatible with Intel’s Pentium®  
series microprocessors.  
The PT7761s features include a  
momentary-interrupt style of short-  
circuit protection, a standby control,  
and a differential remote sense to  
compensate for voltage drop between  
the ISR and load. For additional  
output current the PT7761 can  
operate with up to three current  
boosters.
