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.
