They are 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. NMA0505S NMA0509S NMA0512S NMA0515S NMA1205D NMA1209D NMA1212D NMA1215D NMA1205S NMA1209S NMA1212S NMA1215S 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.
