Description
The PT4711 Excalibur power
module is a 45-watt rated DC/DC
converter that produces two regu-
lated output supply voltages from a
standard (–48 V) telecom central
office supply.
Both of the outputs from this
module are truly independent. Each
is separately regulated and has its
own negative return. This allows the
flexibility of configuring the output
for up to three voltage options. This
includes a complimentary dual ±15-V,
or a single +30-V or –30-V output.
The PT4711 incorporates many
features to simplify system integra-
tion. These include a flexible On/Off
enable control, input under-voltage
lock-out, and over-temperature pro-
tection. All outputs are short-circuit
protected, and internally sequenced
for simultaneous power-up and power-
down.
The module is packaged in a
space-saving solderable copper case,
requires no heat sink, and can occupy
as little as 1.2 in2 of PCB area.
