ISOLATION CHARACTERISTICS
DESCRIPTION
The NMR series of industrial temperature range
DC/DC converters are the standard building blocks
for on-board distributed power systems. They are
ideally suited for providing single rail supplies on
primarily digital boards with the added benefit of
galvanic isolation to reduce switching noise. Sur-
face mount technology and advanced packaging
materials produce rugged reliable performance
over an extended temperature range from -40ºC
to 85ºC.
