DESCRIPTION
The NKA sub-miniature series of industrial
temperature range DC-DC converters are the
standard building blocks for on-board
distributed power systems. The series offers
smaller package size, improved efficiency,
lower output ripple and 3kVDC isolation
capability through the use of state of the art
packaging and technology. 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.

For DIP package style replace suffix S with D, eg NKA0312D.
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 Calculated using MIL-HDBK-217F with nominal input voltage at full load.
2 See derating curve.
3 12V input types have typically 3% less load regulation change.
4 Supply voltage must be discontinued at the end of the short circuit duration.
