PRODUCT OVERVIEW
ISOLATION CHARACTERISTICS
The NMV1 series of extended industrial tempera-
ture range DC-DC converters are the standard
buliding blocks for on-board distributed power
systems. They are ideally suited for providing local
supplies on control system boards with the added
benefit of 3kVDC galvanic isolation to reduce
switching noise.
