APPLICATION NOTES

Minimum load
The minimum load to meet datasheet specifi cation is 10% of the full rated load across the specifi ed input voltage range. Lower than 10% minimum loading will result in
an increase in output voltage, which may rise to typically double the specifi 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
Differential Mode Noise Test Schematic
All measurement to be taken with the following components connected to the UUT as detailed below. 50 Ohm coax cable, solder connections one end, BNC plug at
the other end.

Measured values are multiplied by 10 to obtain the specifi ed values.
1μF X7R multilayer ceramic capacitor rated at minimum 3 x the output voltage of the UUT
10μF tantalum capacitor rated at minimum 1.5 x the output voltage of the UUT with ESR of less than 100 milliohms at 100 kHz e.g. AVX TPS
series.
100nF multilayer ceramic capacitor, general purpose
450 Ohm resistor, carbon fi lm, ±1%
50 Ohm BNC termination
3T of the coax cable through a ferrite toroid eg Ferroxcube TN32/19/13-3E25
Resistive load at the UUT maximum rating. Connections via twisted wires.
