3kv ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER
ExxxxS-1W SERIES
DESCRIPTION
The ExxxxS-1W 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 benefit of galvan ic 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.

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.
