The NMH series of industrial temperature range
DC/DC converters are the standard buliding blocks
for on-board point-of-use power systems. They
are ideally suited for providing dual rail supplies
on single rail boards with the added benefit of
galvanic isolation to reduce circuit noise. All of
the rated power may be drawn from a single pin
provided the total load does not exceed 2 watts.

Pin compatibility with the NMA 1 watt series
ensures minimal effort in upgrading distributed
power systems.
