PT812x Standard Application (See page 4 for PT8124 application schematic)
PT8120 Series
Description
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.
