NME 5V & 12V Series
Isolated 1W Single Output DC/DC Converters
APPLICATION NOTES
Minimum load
The minimum load to meet datasheet speci?cation is 10% of the full rated load across the speci?ed input voltage range. Lower than 10% minimum loading will result in
an increase in output voltage, which may rise to typically double the speci?ed 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 con?guration.
C1
C2
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 100mΩ at 100 kHz
C3 100nF multilayer ceramic capacitor, general purpose
R1 450Ω resistor, carbon ?lm, ±1% tolerance
R2 50Ω BNC termination
T1 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 speci?ed values.
