Pin Function  
The PT7712 Excalibur™ power module  
is a 20-A integrated switching regulator  
(ISR) housed a 27-pin space-saving  
copper package. Operating from a 3.3V  
input bus, the PT7712 produces a tightly  
regulated output voltage that is program-  
mable over the range, 1.3V to 2.05V.  
The output voltage is selected via a  
4-bit code, which is compatible with the  
VRM specifications defined by Intel®.  
This regulator is most suitable for  
microprocessor and DSP applications  
requiring core or I/O logic supply voltages  
as low as 1.3V.
