APPLICATION NOTES

1. Output load requirement

To ensure this module can operate eﬃciently and reliably, the minimum output load may not be less than 10% of the full load during

operation. If the actual output power is low, connect a resistor at the output end in parallel to increase the load.

2. Recommended circuit

If you want to further decrease the input/output ripple, you can increase the capacitance accordingly or choose capacitors with low

ESR (see Figure 2 & Table 2). However, the capacitance of the output ﬁlter capacitor must be appropriate. If the capacitance is too

high, a startup problem might arise. For every channel of the output, to ensure safe and reliable operation, the maximum capacitance

must be less than the maximum capacitive load (see Table 3).

Note: It’s not recommended to connect any external capacitors in

applications with less than 0.5 watt output.
