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 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.
