APPLICATION NOTE
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 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.
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.
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.
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.
