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.

i When operated without additional external load capacitance, the output voltage of the NMA devices is guaranteed to be
within 95% of its steady state value within 100ms after the input voltage has reached 95% of its steady state value,
irrespective of the rise time of the input voltage.
ii 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.
1 Supply voltage must be discontinued at the end of the short circuit duration.
