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 sup-
plies 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.
