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-to­out 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.

Part Numbering
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.
See part numbering chart on this page for other product grades.
