Design Reference
1. Typical application
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.2.
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.
The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat
protection that is connected to the input or output end in series (see Fig. 4).

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, ensuring that the sum of the power consumption is
always maintained at 10% minimum.
