Requirement on output load
this kind of DC/DC converter in addition to a maximum load (namely full load). During
operation, make sure the specified range of input voltage is not exceeded, the minimum
output load is not less than 10% of the full load, and that this product should never be
operated under no load!
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.
Overload Protection
against over-current and short-circuits. The simplest method is to connect a self-recovery
fuse in series at the input end or add a circuit breaker to the circuit.

Filtering
and ripple, a filtering capacitor may be added to
the DC/DC output end and input end to reduce
the noise and ripple. 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
the external capacitor table.
It’s not recommended to connect any external capacitor
in the application field with less than 0.5 watt output。
network may be connected to the input and
output ends of the DC/DC converter, which may
produce a more significant filtering effect. 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 (Figure 1).
