    Products Detail

    The PT4400 series are single-output isolated DC/DC converters in a compact 21-pin low-profile (12mm) package. Rated up to 75W with load currents as high as 20A, the output voltage is set via a 5-bit input code. They operate from a standard 48-V telecom supply and occupy only 3.9in² of PCB area, providing a compact and flexible high-output power source for high-end microprocessors, DSPs, general purpose logic and analog in distributed power applications for telecom and computing.

    Key Features

    • Up to 75W Output, Input Voltage Range: 36V to 75V, Programmable Output Voltage, 91% Efficiency (PT4403), 1500 VDC Isolation, On/Off Control, Over-Current Protection, Differential Remote Sense, Output Over-Voltage Protection, Over-Temperature Shutdown, Undervoltage Lockout, Low Profile Package (12mm), Compact PCB Layout, Solderable Copper Case, Agency Approvals Pending
