TYPICAL CHARACTERISTICS
Recommended testing 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 (Figure1).

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’s not recommended 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 (Figure2).

APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently 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,
or use our company’s products with a lower rated output power.

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.
