PT4801—48V
Description
The PT4801 Excalibur module is an
isolated triple-output DC/DC converter
that provides +15V, +3.3V, and +1.5V
power supply voltages from a standard
(-48V) telecom central office (CO) supply.
A typical application is a chip-set for an
8 or 16-channel ADSL/DSL line card, or
other mixed signal circuitry. The output
voltage combination provides power for a
processor core, digital logic, and analog
support circuitry. The Vo2 and Vo3 outputs
are also designed to meet the power-up/
down sequencing requirements of popular
DSP ICs.
The PT4801 is housed in a space-
saving solderable copper case. A heatsink
is not required. The vertical configura-
tion occupies only 1.6 in2 of PCB area.
