APPLICATION NOTE
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; or use our company’s
products with a lower rated output power (G_S-1W & H_S-1W).
Recommended testing and application circuit
If you want to further decrease the
input/output ripple, an “LC” filtering network may
be connected to the input and output ends of the
DC/DC converter, see (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
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 greatest capacitance of its filter
capacitor sees (Table 1).

It’s not recommend 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 (Figure 2).

Overload Protection
Under normal operating conditions, the output
circuit of these products 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.
No parallel connection or plug and play.
