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
500
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.
