APPLICATION NOTES
1. Requirement on output load
To ensure this module can operate efficiently and reliably, the minimum output load cannot be less than 10% of the full load during
operation. If the actual output power is small, please connect a resistor at the output end in parallel to increase the load.
2. Recommended circuit
This series has been tested according to the following recommended testing circuit before leaving the factory. This series should be
tested under load (see Figure 3). If you want to further decrease the input/output ripple, you can increase capacitance properly or
choose capacitors with low ESR (see Table 3). However, the capacitance must not exceed the maximum capacitive load or a start-up
problem might arise (see Table 4).

1. Minimum load shouldn't be less than 10%, otherwise ripple may increase dramatically. Operation under minimum load will not damage the converter, however, they may not meet all specifications listed.
2. Maximum capacitive load is tested at input voltage range and full load.
3. All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
