description
The NMH series of industrial temperature range
DC-DC converters are the standard building
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 2W.
Pin compatibility with the NMA 1 watt series
ensures minimal effort in upgrading distributed
power systems.
