Product Overview

These DC-DC converter modules use advanced powerprocessing, control and packaging technologies to providethe performance, flexibility, reliability and cost effectivenessof a mature power component. High frequency Active Clampswitching provides high power density with low noise andhigh efficiency.

 

Product’s Introduction

The MT series is an independently regulated single output converter that uses the industry nonstandard brick packagesize. Integral PCB transformer/inductor is used for all models in this series. This new design technique has greatlyimproved the magnetic coupling, reduced switching spike and provided performance consistency. It also streamlines theproduction process by completely eliminating the hand-wind magnetic assembly process from production lines.
