The PT7615 power module is a 20-A  
fully integrated switching regulator (ISR)  
housed in a 27-pin aluminum SIP package.  
Operating from a 5V-input bus, the  
PT7615 produces a tightly regulated  
supply voltage that is programmable over  
the range, 1.075V to 1.85V. The output  
voltage is selected via a 5-bit code. The  
code adjusts the voltage in steps of 25mV  
and is VRM 9.0 compatible.

This regulator is most suitable for  
applications that employ microprocessor  
and DSP products that require core supply  
voltages as low as 1.075V.  
The PT7615 includes a Shutdown  
control, Differential Remote Sense, and  
Short-Circuit Protection.
