Description

The PTMA40XX is a series of 10-W rated isolated dc/dc converters, designed to operate from a standard -48-V telecom central office supply. Housed in an industry standard 1.1 in × 1.0 in (27.94 mm × 24.38 mm) package, this series of isolated modules is set to one of the common intermediate bus voltages of 3.3 V, 5 V, or 12 V.

The PTMA40XX series includes many features expected of high-performance dc/dc converter modules. Operational features include an input undervoltage lockout (UVLO) and a dual-logic output enable control or synchronization option. Overcurrent protection ensures survival against load faults.

Typical applications include distributed power architectures in both telecom and computing environments, power over ethernet, and particularly complex digital systems requiring multiple power supply rails.
