Calculated using MIL-HDBK-217FN2 calculation model with nominal input voltage at full load. All specications typical at TA=25C, nominal input voltage and rated output current unless otherwise specied. The NMA 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 benet 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.
