DESIGN CONSIDERATIONS
1) Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 10% of the full load. If
the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load.
2) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to add a circuit
breaker to the circuit.

3) Recommended circuit
If you want to further decrease the input/output ripple, an capacitor filtering network may be connected to the input and output ends of the DC/DC
converter, see (Figure 2).
It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every
channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Table 1).

It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output.
4) Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and over-current protection is a linear regulator and an capacitor filtering network with
overheat protection that is connected to the input or output end in series (Figure 3), the recommended capacitance of its filter capacitor sees (Table 1),
linear regulator based on the actual voltage and current to reasonable selection.
