Pin Function  
The PT7711 Excalibur™ power module  
is a 20-A integrated switching regula-  
tor (ISR) housed a 27-pin space-saving  
copper package. Operating from a +5V  
input bus, the PT7711 produces a tightly  
regulated output voltage that is program-  
mable over the range, 1.3V to 3.5V. The  
output voltage is selected via 5-bit input  
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 volt-  
ages as low as 1.3V.
