ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER AxxxxS-1W SERIES DESCRIPTION The AxxxxS-1W 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 galvan ic 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.
