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. Overload Protection
Under normal operating conditions, the output circuit of this product has no protection against overload. The simplest method to add
this is to add a circuit breaker to the circuit.
3. 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 & 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).

Note: It’s not recommended to connect any
external capacitors in applications with
less than 0.5 watt output.
Note:
1. Operation under minimum load will not damage the converter; however, they may not meet all specifications listed.
2. Max. capacitive load tested at input voltage range and full load.
3. It is recommended to use either ceramic capacitors or electrolytic capacitors on the input and the output. Using tantalum capacitors may increase the risk of failure.
4. All specifications measured at: Ta=25°C, humidity<75%, nominal input voltage and rated output load, unless otherwise specified.
