Description
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
drop between the regulator and load.
