input/output ripple, an “LC” filtering network may
be connected to the input and output ends of the
DC/DC converter, see (Figure 1).
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. It’s not recommended to connect any
external capacitor in the application field.
regulation,
protection is a linear voltage regulator with
overheat protection that is connected to the input
or output end in series (Figure2).
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.
Requirement on output load
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.
