description
The NMA series of DC-DC converters are
the standard building blocks for on-board
distributed power systems. They are ideally
suited to 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 1 Watt.
