Standard Application
PT7761—5V
Description
The PT7761 is a high performance
integrated switching regulator (ISR),
housed in a solderable, 31-pin space-
saving copper package. Operating
from and input voltage of +5V, the
PT7761 provides up to 40A of low-
voltage power for the industry’s latest
DSPs, and -Processors.
The PT7761 performance extends
both the flexibility and output current
range of the “Big Hammer” series of
Plug-in Power modules, and provides
a state-of-the-art solution for highly
integrated digital systems that de-

mand high power supply currents at
low output voltages.
The PT7761 is programmable from
1.3V to 3.5V via a 5-bit input, which
is compatible with Intel’s Pentium
series microprocessors.
The PT7761’s features include a
momentary-interrupt style of short-
circuit protection, a standby control,
and a differential remote sense to
compensate for voltage drop between
the ISR and load. For additional
output current the PT7761 can
operate with up to three current
boosters.
