Product Overview

This DC-DC converter module uses

2nd Generation power processing, control

and packaging technologies to provide the

performance, flexibility and cost effectiveness

expected of a mature power component.

For example, a plated-cavity core transformer

couples widely separated primary and

secondary windings, resulting in low in-to-

out parasitic capacitance and noise.

High frequency ZCS/ZVS switching,

advanced power semiconductor packaging

and thermal management provide high

power density with low temperature

gradients. Extensive use of silicon

integration results in 1/3 the part count

of a 1st Generation converter.
