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 effi ciency, 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 benefi t 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 1 watt.
