Ordering Information

Description

PT8001o = 1.3 to 3.5 Volts

PT8002o = 1.075 to 1.850 Volts

The PT8000 series is a 60 A high-

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.

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
