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.

When operated with additional external load capacitance the rise time of the input voltage will determine the
maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the
greater the maximum value of the additional external capacitance for reliable start up.
