CMR Series
Isolated 0.75W Single and Dual Output Isolated DC/DC Converters
SELECTION GUIDE
FEATURES
Single or Dual Isolated Outputs
1kVDC or 3kVDC options
Wide temperature performance at full
0.75W load -40 C to 85C°
Industry Standard Pinouts
5V, 12V and 24V Inputs
5V, 12V and 15V Outputs
Pin compatible with NMR, MER1, MMV,
MEV1, NMK, MEV3, NMV series.
DESCRIPTION
The CMR series are a cost effective 0.75W DC/DC
converter series, in an industry standard package
with industry standard pinouts., 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.
