ISOLATED UNREGULATED DUAL OUTPUT DC/DC CONVERTER
AxxxxS-1W SERIES
DESCRIPTION
The AxxxxS-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.
