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 package
size. Integral PCB transformer/inductor is used for all models in this series. This new design technique has greatly
improved the magnetic coupling, reduced switching spike and provided performance consistency. It also streamlines the
production process by completely eliminating the hand-wind magnetic assembly process from production lines.
