PT4103A [Texas Instruments]

Designed to operate from a standard 48V telecom bus, these modules employ switching frequencies of up to 850kHz, planar magnetics, and surface-mount construction. They provide 15W output power with input voltage range of 36V to 75V, 1500 VDC isolation, current limit, short-circuit protection, and over-temperature shutdown. Certified to UL1950, CSA 22.2 950, and EN60950 standards for Telecom, Industrial, Computer, Medical, and distributed power applications requiring input-to-output isolation.
