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 NKA0303S 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 NKA0303S  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.
