The PTMA40XX is a series of isolated dc/dc converters rated at 10 w and designed to operate from standard -48v telecom central office power. The series isolation modules are available in industry standard 1.1 in x 1.0 in (27.94 mm x 24.38 mm) packages set to one of the common intermediate bus voltages of 3.3 V, 5 V or 12 V.
The PTMA40XX series includes many features of high performance dc/dc converter modules. Operational features include input undervoltage lock (UVLO) and dual logical output enable control or synchronization options. Overcurrent protection ensures survival under load failure.
Typical applications include distributed power architectures in telecommunications and computing environments, power over Ethernet, and particularly complex digital systems that require multiple power tracks
