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.

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.
