(See p.3 for PT8104 application schematic)
PT8100 Series
Description
The PT8100 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. Modules are avail-
able for operation from either a 3.3V
or 5V nominal input bus voltage.
Each provides up to 40A of output
current at output voltages as low
as 0.8V. The output voltage is pro-
grammable via a 5-bit input code.
The PT8100 series 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 modules are designed for high-
end computing and signal processing
applications, both of which demand
high output currents at low supply
voltages.
The modules have a number of
standard features to facilitate system
integration. These include short-
circuit protection, thermal shutdown,
standby (On/Off) control, and an
output remote sense to compensate
for voltage drop between the regu-
lator and the load. In addition, the
voltage programming codes are
compatible with Intel’s VRM
specifications.
