APPLICATION NOTES
1. Output load requirement
To ensure this module can operate efficiently and reliably, the minimum output load may not be less than 5% 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
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 and Table 3). If you want to further decrease the input/output ripple, you can increase the
capacitance accordingly or choose capacitors with low ESR. 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 4).

When open or applied high impedance, the converter will turn on. When it’s pulled high, the converter will shutdown. The input
current should between 5~10mA. Exceeding the maximum 20mA will cause permanent damage to the converter. The value for R can
be derived as follows:

1. Minimum load shouldn't be less than 5%, 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.
