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.

The PT7712 incorporates output

short-circuit protection, and a differential

remote sense to compensate for voltage
