Design Reference
1. Typical application
If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals, see Fig.2.
Moreover, choosing suitable filter capacitor is very important , start-up problems may be caused by too large capacitance.To ensured the modules
running well, the recommended capacitive load values as shown in Table 1.

3. Output load requirements
To ensure the module work efficiently and reliably, during the operation, the min. output load should be no less than 10% of the full load. If the actual
output power is low, please connect a resister to the output terminal in parallel, with a recommenced resistance which is 10% of the rated power, and
derating is required during operation.
