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 (Table 1).

It not recommend to connect any external capacitor in the
application field with less than 0.5 watt output.
Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and
over-current protection is a linear voltage regulator with overheat
protection that is connected to the input or output end in series (Figure 2).
Dual Output
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
Note:
1. All specifications measured at Ta=25, humidity<75%,nominal input
voltage and rated output load unless otherwise specified.
2. Only typical models listed, other models may be different,
please contact our technical person for more details.
3. Operation under minimum load will not damage the
converter; However, they may not meet all specification listed.
