App Notes
Requirement on output load
To ensure this module can operate efficiently and reliably, during operation, the
minimum output load is not less than 10% of the full load, and that this product
should never be operated under no-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.
Recommended testing circuit
If you want to further decrease the
input/output ripple, an “LC” filtering
network may be connected to the
input and output ends if the DC/DC
converter, see Figure on the right
hand side.
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 proper. If the
capacitance is too big, a start-up problem might arise. For every channel of output,
provided the safe and reliable operation is ensured, the greatest capacitance of its
filter capacitor sees (see Table).

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 input or output
end in series.

It’s not recommend to connect any external
capacitor in the application field with less
than 0.5 watt output.
Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection against
over-current and short-circuits. The simplest
method is to connect a self-recovery fuse in series
at the input end or add a circuit breaker to the
circuit.
No parallel connection or plug and play.
