DESCRIPTION

The NMR series of industrial temperature range

DC/DC converters are the standard building blocks

for on-board distributed power systems. They are

ideally suited for providing single rail supplies on

primarily digital boards with the added beneﬁt of

galvanic isolation to reduce switching noise. Sur-

face mount technology and advanced packaging

materials produce rugged reliable performance

over an extended temperature range from -40ºC

to 85ºC.

NMR Series Isolated 1W Single Output 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%. Capacitive loading and start up Typical start up times for this series, with a typical input voltage rise time of 2.

NMR Series Isolated 1W Single Output 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. The voltage rating should be at least twice (except for 15V output), the rated output voltage of the DC/DC converter.
