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
integration results in 1/3 the part count
of a first generation converter.
*Part Numbering
V48 A 12C 500 A
For pin styles see page 6. 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”.
See page 7 for dimensions.
