Typical Application
PT4840 Series—48V
Description
The PT4840 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 65W,
these regulators are appropriate for
powering both analog and mixed-
signal circuitry. A typical application
is a chip-set for an ADSL/DSL line
card.
The output voltage combinations
offered by the PT4840 series provide
power for a low-voltage processor
core, the associated digital circuitry,
and analog support circuitry.
The PT4840 series incorporates
many features to simplify system
integration. These include a flexible
On/Off control, over-temperature
protection, and an input under-
voltage lock-out. All outputs are
current limited and short-circuit
protected. In addition, the low-
voltage outputs for processor core
and digital circuitry meet the power-
up and power-down sequencing
requirements of popular DSP ICs.
The PT4840 series is housed in
a space-saving solderable case. The
module requires no external heat sink
and can occupy as little as 1.97 in
2
of
PCB area.
