DESCRIPTION: dc-dc converter
- 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).
APPLICATION NOTES:
- Requirement on output load
To ensure this module can operate efficiently and reliably,
the minimum output load should not be less than 10% of the
full load. Also, this product should never be operated under
no load conditions. If the actual output power is too small,
please connect a resistor with proper resistance at the output
end in parallel to increase the load.

- Overload protection
No parallel connection or plug and play.
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 to add a circuit breaker to the circuit.
- Recommended 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 that safe and reliable
operation is ensured, the recommended capacitance of its
filter capacitor see (Table 1).

It is not recommended to connect any external capacitor in the
application field with less than a 0.5 watt output.
