Design Reference
1. Typical application circuit
Input and/or output ripple can be further reduced, by connecting a filter capacitor from the input and/or output terminals to ground as
shown in Fig.3.
Choosing suitable filter capacitor values is very important for a smooth operation of the modules, particularly to avoid start-up problems
caused by capacitor values that are too high. For recommended input and output capacitor values refer to Table 1.

3. Output load requirements
For a reliable and efficient operation of the converter, the minimum load should never be less than 10% of the rated output load. If the total
required output power is below 10%, a parallel bleeding resistor is required on the output (The sum of the efficient power and resistor
consumption power is not less than 10%).
