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.

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.
