Description
The PT8000 series is a 60 A high-
performance, Integrated Switching
Regulator (ISR) housed in a single
low-profile 44-pin SIP package.
Operating from an input voltage of
+5V, the PT8000 series offers a
state-of-the-art “Plug-in Power”
solution for highly-integrated
digital systems that demand high
power supply currents at low voltages.
The output voltage from these
modules is programmable over a
preset range via a 5-bit input. The
PT8001 may be set from 1.3V to
3.5V which is compatible with Intel’s
Pentium Pro μ-processors. The
output voltage of the PT8002 is
programmable from 1.075V to 1.85V.
The PT8000 series incorporates
many features to facilitate system

integration. Output short-circuit
protection and over-temperature
shutdown enables these modules to
survive any load fault. Two self-
diagnosotic signals, “Power Good”
(PWRGD*) and “Over-Voltage
Flag” (OVF*) are provided. And a
unique tracking feature allows the
output to be synchronized to a master
ramp voltage during power-up.
Other features include a standby
input, and a differential remote sense
to compensate for voltage drop between
the ISR and load.
A low ESR capacitance of 2000μF
is required at the input for proper
operation.
