Summary
The IMR 40 series of DC-DC converters have been devel-
oped for powering commercial type of electronic circuits,
e.g. telephone systems components, industrial controllers
and small appliances. They are suitable for applications
with standard battery voltages. The IMR 40 converters fea-
ture good efficiency and good dynamic response to load
changes and at start-up. The IMR 40 modules are short-cir-
cuit proof.
