APPLICATIONS
The TMA-XS(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 single rail supplies on primarily digital boards

Input current full load
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.
