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.

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”.
