Description
The PT6701 Excalibur鈩?power
module is a fully integrated 13-A
switching regulator housed in a space-
saving solderable package. The PT6701
operates from a +5V input to provide
a high-performance low-voltage power
source for the industry鈥檚 latest 碌Ps,
DSPs, and bus drivers. The PT6701
is programmable from 1.3V to 3.5V
with a 5-bit input, which is compatible
with Intel鈥檚 Pentium廬 II Processor.
The PT6701 has output short
circuit protection, a 鈥淧ower Good鈥?/div>
output, and an over-voltage protection
(OVP) drive.
