Typical Application
PT4820 Series
Description
The PT4820 Excalibur power
modules are a series of isolated triple-
output DC/DC converters that
operate from a standard (–48V)
central office supply. Rated for up to
35W, these regulators are ideal for
powering many mixed logic appli-
cations. The triple-output voltage
combination allows for a compact
multiple-output power supply in a
single low-profile DC/DC module.
The available output voltage
options include a low-voltage power
bus for a DSP or ASIC core, and
two additional standard logic supply
voltages.
The PT4820 series incorporates
many features to simplify system
integration. These include a flexible
On/Off enable control, an input
under-voltage lock-out, and over-
temperature protection. All outputs
have short-circuit protection and are
internally sequenced to meet the
power-up and power-down require-
ments of popular DSP ICs.
The PT4820 series is housed in
a space-saving solderable case. The
module requires no external heat sink
and can occupy as little as 1.3 in2 of
PCB area.
