Description

Ordering Information

Pin-Out Information

The PT4400 series of power modules are single-

output isolated DC/DC converters, housed in a

compact 21-pin low-profile (12mm) package.

These modules are rated up to 75W with load

currents as high as 20A. The output voltage is set

within a pre-defined range via a 5-bit input code.

The PT4400 series operates from a standard

48-V telecom CO supply and occupies only 3.9in²

of PCB area. These modules offer OEMs a compact

and flexible high-output power source for use with

high-end microprocessors, DSPs, general purpose

logic and analog. They are suitable for distributed

power applications in both telecom and computing

environments.

Features include output over-current protection,

on/off control, output over-voltage protection

(OVP), over-temperature shutdown, under-volt-

age lockout (UVLO), and an output differential

remote sense. The modules are fully integrated

for stand-alone operation, and require no additional

components.

PT 4401r = 1.3 to 3.5 Volts

PT 4402r = 1.05 to 1.75Volts

PT 4403r = 3.4 to 5.7 Volts
