Refer to the Cout in Fig.3
Note: Product bare input of 3.3V, 5V, 12V already meet CLASS A,
increase the capacitor margin increase.

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.
