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

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.
(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.
