Recommended circuit
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.

Output Voltage Regulation and Over-voltage
Protection Circuit
regulation,
protection is a linear voltage regulator with
overheat protection that is connected to the input
or output end in series (Figure 2).
Overload Protection
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.
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.
