Description
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.
The PT7711 regulator incorporates
output short-circuit protection, and a
differential remote sense to compensate
for voltage drop between the regulator
and load.
