Description
The PT6725 series of power modules
are integrated switching regulators (ISRs),
housed in a 17-pin space saving solderable
copper package. These modules operate
off a 12V input power bus to provide up to
14A of low-voltage power for the indus-
try’s latest high-speed, DSPs, Ps, and
bus drivers. The series includes the stan-
dard output bus voltage options, ranging
from 1.2V to 5.0V. The factory preset
voltage can also be adjusted over a limit-
ed range with a single external resistor.
Features include a Standby function,
output short circuit protection, and a
differential Remote Sense to compensate
for voltage drop between the ISR and
load. The modules are available in both
through-hole and surface mount configu-
rations.
