Product Overview
This DC-DC converter module uses
2nd Generation power processing, control
and packaging technologies to provide
the performance, flexibility and cost effec-
tiveness 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.
