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.
