Input Reflected Ripple Current Test Step

Input reflected ripple current is measured through

a source inductor Lin(12uH) and a source capacitor

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.

1. Operation at no load condition will not damage the produce ; however, it will not meet all specifications.

2. One load is 25% to 100% load, the other load is 100% load, the output voltage variable rate is within ±5%.

3. Measured with 20MHz bandwidth .

4. Test by minimal Vin and constant resistive load.

5. Test by normal Vin and 100%-25% load,25% Ioad step change .

8. Exceeding the absolute ratings of the unit could cause damage.

It's not allowed for continuous operating ratings.

9. 25% minimum loading is needed.

10. Input filter components are be required to help meet conducted

emission class A, which application refer to the EMI Filter of design & feature configuration.

11. An external filter capacitor is required if the module has to meet IEC61000-4-4 and IEC61000-4-

5. The filter capacitor RSG suggest: Nippon - chemi - con KY series, 220uF/100V.
