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.
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 the
safe and reliable operation is ensured, the
recommended 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
(Figure 2).

Overload Protection
Under norm al 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.
