Recommended circuit
If you want to further decrease the
input/output ripple, an LCfiltering 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 LCfiltering 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).

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
companys products with a lower rated output power.
Overload Protection
Under normal operating conditions, the
output circuit of these products has no
protection against over-current. 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.
No parallel connection or plug and play.
