Description
The PT4485 Excalibur module
combines state-of-the-art power
conversion technology with un-
paralleled flexibility. Operating off a
standard 48V telecom input, the PT4485
provides a full 100W output at load
currents up to 8.5A, and over the
programmable output voltage range of
6.5V to 17.5V.
The PT4485 features high efficiency,
ultra-fast transient response, and the
capability for true N+1 current sharing.
This product also includes output short
circuit and over-temperature protection.

Programming pins, VID0–VID4, are shown
configured for Vo =12.0V
For normal operation, pin 3 (Inhibit) must be
connected to –Vin.
For operation in N+1 configuration, consult the
related application note.
Pins 6 & 26 are used for N+1 configurations only.
