ISOLATED UNREGULATED DUAL OUT PUT DC/DC CONVERTER
AxxxxS-2W SERIES
DESCRIPTION
The AxxxxS -2W series of industrial temperature range DC/DC converters are the standard building blocks for
on-board point-of-use power systems. They are ideally suited for providing dual rail supplies on single rail
boards with the added benefit of galvanic isolation to reduce circuit noise. All of the rated power may be drawn
from a single pin provided the total load does not exceed 2 watts. Pin compatibility with the AxxxxS-1W series
ensures minimal effort in upgrading distributed power systems.

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.
