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 2.2μs and output capacitance of 10μF, are shown in the table below. The product

series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.

Ripple & Noise Characterisation Method

Ripple and noise measurements are performed with the following test conﬁguration.

1μF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter

10μF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC/DC converter with an ESR of less

than 100mꢀ at 100 kHz

100nF multilayer ceramic capacitor, general purpose

450ꢀ resistor, carbon ﬁlm, 1% tolerance

50ꢀ BNC termination

3T of the coax cable through a ferrite toroid

RLOAD

Resistive load to the maximum power rating of the DC/DC converter. Connections should be made via twisted wires

Measured values are multiplied by 10 to obtain the speciﬁed values.
