Description
The PT6722 is a fully integrated
14-A switching regulator housed in a
space-saving solderable package. The
PT6722 operates from 12V to provide
a high-performance low-voltage
output that is programmable over the
range 1.1V to 1.85V. This output
voltage range is specifically suited to
high performance 碌P and DSP appli-
cations that require core supply
voltages below 1.3V. The voltage
control inputs are also TTL compatible.
Additional features include output
short circuit protection, a 鈥淧ower
Good鈥?output, and an over-voltage
protection (OVP) drive.
