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. 1 2 4 5 6 V GND IN –V 0V +V Notice : This is not a final specification. Some parametric limits may be subject to change.

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 Supply voltage must be discontinued at the end of the short circuit duration. 2 Newport Components Isolation Capacitance (pF) 28 32 34 36 28 32 34 36 33 46 55 54 33 46 55 54 Isolated 1W Dual Output DC-DC Converters family characteristics - input Specifications typical at T =25°C, nominal input voltage and rated output current unless otherwise specified.
