Product Overview
This DC-DC converter module uses
second 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

For long pin configuration add “L” to the
end of the part number. Slotted baseplate
(style 1) requires no designator. For
threaded baseplate add a “2” to the end of
the part number. For thru-hole, add a “3”.
