DESCRIPTION

The NMA series of industrial temperature

range DC-DC converters are the standard

building blocks for on-board distributed

power systems. They are ideally suited for

providing dual rail supplies on primarily

digital boards with the added benefit of

galvanic isolation to reduce switching noise.

All of the rated power may be drawn from

a single pin provided the total load does not

exceed 1watt.

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.
