APPLICATIONS
The B-XLS(D)-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 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.
