Summary
The IMP 12 series of primary controlled single transistor
forward DC-DC converters have been developed for
powering commercial type of electronic circuits, e.g. tel-
ephone systems components, industrial controllers and
small appliances. They are suitable for applications with
standard battery voltages. The IMP 12 converters feature
good efficiency and good dynamic response to load
changes and at start-up. The IMP 12 modules are short-cir-
cuit proof.
