The CME series are a cost effective 0.75W DC/DC
converter series, in industry standard packages
with industry standard pinout., Popular input and
output voltages are available as a lower power
alternative to a 1W DC/DC converter. The galvanic
isolation allows the device to be configured to
provide an isolated negative rail in systems where
only positive rails exist. The wide temperature
range guarantees startup from –40°C and full 0.75
watt output at 85°C.
