APPLICATIONS
The A_X(S)D 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 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 1 Watt.
