Description
These 12 Watt Single Output DC/DC converters are designed
for telecommunications, industrial controls, medical equipment
and instrumentation systems. The converters feature very
wide input voltage ranges.
The converter consists of a hi-speed chopper circuit using
state-of-the-art MOSFET technology, isolation transformer,
and high regulation linear post regulator. These provide very
low noise and ultra stable output voltages.
