The series 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 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.

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. 1 Calculated using MIL-HDBK-217F with nominal input voltage at full load. 2 See derating curve. 3 12V input types have typically 3% less load regulation change. 4 Supply voltage must be discontinued at the end of the short circuit duration. All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
