Product Overview

These DC-DC converter modules use 
advanced power processing, control and
packaging technologies to provide the
performance, flexibility, reliability and cost effec-
tiveness of a mature power component. 
High frequency ZCS/ZVS switching provides
high power density with low noise and high
efficiency.

Applications

Off-line systems with PFC front ends, industrial
and process control, distributed power, medical,
ATE, communications, defense, aerospace
For details on proper operation please refer to the

Design Guide & Applications Manual for Maxi,
Mini, Micro Family.
