Description

Ordering Information

The PT8120 Excalibur™ power

modules are a family of high-output,

high-efficiency, fully integrated

switching regulators (ISRs), housed

in a solderable 31-pin space-saving

copper package. These modules

operate from a nominal input voltage

of +12V to provide up to 30A of

output current at output voltages as

low as 0.8V. The output voltage is

programmable via a 5-bit input code.

The PT8120 family incorporates

a state-of-the-art, 2-phase, multiple

power path topology. This extends

the output current range while pro-

viding superior transient response

and input current ripple performance.

The PT8120 family is designed

to power high-end computing and

signal processing applications, all of

which demand high output currents

at low supply voltages.

The modules have a number of

features to facilitate system integra-

tion. These include over-current

protection, thermal shutdown, an

on/off standby control, and an output

remote sense to compensate for

voltage drop between the regulator

and the load. In addition, the volt-

age programming codes for the

PT8121, PT8122, & PT8124 are

compatible with Intel’s® VRM

specifications.

PT 8121r = 1.3V

to 3.5V

PT 8122r = 1.075V to 1.85V

PT 8123r = 0.8V

to 1.575V

PT 8124r = 1.05V to 1.825V

PT 8125r = 4.5V to 7.6V
