PT4401N [Rochester]

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-voltage lockout (UVLO), and an output differential remote sense. The modules are fully integrated for stand-alone operation, and require no additional components.
