DC/DC Converter, Isolated, 48VDC Input

Manufacturer's part number :


Manufacturer SynQor


Description :

The PowerQor single output DC-DC converters for the telecom/networking markets are composed of next-generation, board-mountable, isolated, fixed switching frequency DC-DC converters that use synchronous rectification to achieve extremely high power conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. All of the power and control components are mounted to the multi-layer PCB substrate.
