DESCRIPTION

The NMR 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 single rail supplies on primarily

digital boards with the added benefit of

galvanic isolation to reduce switching noise.

Surface mount technology and advanced

packaging materials produce rugged reliable

performance over an extended temperature

range from –40°C to 85°C.

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.
