TEST CONFIGURATIONS
Input Reflected Ripple Current Test Step
Input reflected ripple current is measured through
a source inductor Lin(12uH) and a source capacitor
Cin(47uF, ESR<1.0Ù
at 100KHz) at nominal input and
full load.

EMI Filter
Input filter components (C1, L ) are used to help
meet conducted emissions requirement for the module.
These components should be mounted as close as
possible to the module; and all leads should be minimized
to decrease radiated noise.

NOTE
1.Ripple/Noise measured with 20MHz bandwidth.
2.Tested by minimal Vin and constant resistive load.
3.Measured Input reflected ripple current with a simulated source inductance of 12uH.
4.Exceeding the absolute ratings of the unit could cause damage. It is not allowed for continuous operating.
5.Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
6 . Input filter components are be required to help meet conducted emission class B, which application refer to the EMI Filter of design &
feature configuration.
7. An external filter capacitor is required if the module has to meet IEC61000-4-4 and IEC61000-4-5.
The filter capacitor Motien suggest: Nippon - chemi - con KY series, 470uF/100V.
