APPLICATION NOTE
RECOMMENDED CIRCUIT
1) Requirement on output load
To ensure this module can operate efficiently and reliably, a minimum load is specified
for 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 could not be less than 10% of the full load. If the actual output

power is very small, please connect a resistor with proper resistance at the output end
(Figure 1)
in parallel to increase the load, or use our company’s products with a lower rated output
power.

2) 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).
3) 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).
4) Overload Protection
Under normal operating conditions, the output circuit of these products has no
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.

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

Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the
life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
3. Only typical models listed, other models may be different, please contact our technical person for more details.
