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.

This converter is manufactured in a

state-of-the-art automated manufacturing

facility on a short-cycle-time robotic line

having a capacity of one module every ten

seconds. In-line process controls are

designed to achieve low defect rates and

consistent quality. A comprehensive CIM

system controls the dispatching, assembly

and testing of each module, enabling small

lots to be manufactured as efficiently as

hundreds-of-thousands of units.
