*Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of Power
Converter section, application notes.
Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.
2. See below recommended circuits for more details.
3. 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

APPLICATION NOTE
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 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 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.
Recommended and 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 (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 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).
