PQ48025HKx20 DC-DC Converter








DC-DC Converter

Product Details

The PQ48025HKA20 PowerQor™ Kilo converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high 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. The Kilo series converters offer significant useable output current in an economical standard “half-brick” module. The Kilo units also feature active current sharingfor N+1 and parallel applications.
