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.

CMR Series Isolated 0.75W Single and Dual Output Isolated DC/DC Converters APPLICATION NOTES Minimum load The minimum load to meet datasheet speciﬁcation is 10% of the full rated load across the speciﬁed input voltage range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically double the speciﬁed output voltage if the output load falls to less than 5%.

CMR Series Isolated 0.75W Single and Dual Output Isolated DC/DC Converters APPLICATION NOTES (continued) Output Ripple Reduction By using the values of inductance and capacitance stated, the output ripple at the rated load is lowered to 5mV p-p max. Component selection Capacitor: It is required that the ESR (Equivalent Series Resistance) should be as low as possible, ceramic types are recommended.
