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. Surface mount technology and advanced

packaging materials produce rugged reliable

performance over an extended temperature range

from -40ºC to 85ºC. For the NMR100PC protection

is continuous and auto-resetting on removal of the

short circuit.
