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).

It’s not recommended to connect any external
capacitor in the application field with less
than 0.5 watt output.
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.
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.
