Product Overview
These DC-DC converter modules use advanced power
processing, control and packaging technologies to provide
the performance, flexibility, reliability and cost effectiveness
of a mature power component. High frequency Active Clamp
switching provides high power density with low noise and
high efficiency.
Product’s Introduction
The XD series is an independently regulated single output converter that uses a industry nonstandard brick package. The very high efficiency is a result of ENARGY CORP patented topology that uses synchronous rectification and an innovative construction design to minimize heat dissipation and allow extremely high power densities. The power dissipated by the converter is so low that a heat sink 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 with highyield surface mount technology, resulting in a more reliable product.
