DC/DC Converter

Product Details

The PQ60260HTB10 PowerQor® Tera converter is a nextgeneration, 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. However, this unit provides a baseplate for clamshell applications and optional heatsinking in severe thermal environments. The Tera series converters offer the maximum usable current output for any standard “half-brick” module. The Tera units also feature active current sharing for N+1 and parallel applications. RoHS Compliant see last page.

Operational Features

• Ultra-high efficiency, 92% at full rated load current
