APPLICATION NOTES
1. Requirement on output load
To ensure that this module can operate efficiently and reliably, a minimum load is specified in addition to a maximum load. During
operation, make sure that the specified range of input voltage is not exceeded and that the minimum output load is not less than 10%
of the full load. This product should never be operated under no load. If the output of the power supply is small, please connect a
resistor with proper resistance at the output end in parallel to increase the load.
2. Recommended testing and application circuit
If you want to further decrease the input/output ripple, an "LC" filtering network can be connected as per Figure 1.

It should also be noted that the inductance and the frequency of the “LC” filtering network should be staggered with the dc-dc
frequency to avoid mutual interference. However, the capacitance of the output filter capacitor must be correct. If the capacitance
is too large then a startup problem may arise. The maximum capacitance for each output is 100 µF. For every channel of output,
provided that safe and reliable operation is ensured, the recommended capacitance of its filter capacitor should be what is shown in
Table 1.

It is not recommended to connect any external capacitor in the application field with less than a 0.5 W output.
3. Output voltage regulation and over-voltage protection circuit
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 output end in series. (Figure 2)

4. Overload protection
Under normal operating conditions, the output circuit of these dc-dc converters has no protection against overload. The simplest
method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit.
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. All specifications measured at: Ta=25°C, humidity<75%, nominal input voltage and rated output load, unless otherwise specified.
