They are ideally suited for providing single rail supplies on primarily digital boards with the added benefit of galvanic isolation to reduce switching noise. Surface mount technology and advanced packaging materials produce rugged reliable performance over an extended temperature range from –40°C to 85°C.

The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.
