Recommended 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 recommended 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.
Input Over-voltage Protection Circuit
The simplest device for input over-voltage
protection is a linear voltage regulator with overheat
protection that is connected to the input end in series
(Figure 2).

When the environment temperature is higher
than 71°C, the product output power should be
less then 60% of the rated power.
APPLICATION NOTE
No parallel connection or plug and play.
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.
