APPLICATION NOTE
Filtering
In some circuits which are sensitive to noise and ripple, a filtering capacitor may be added to the DC/DC output end and input end to reduce the noise
and ripple. 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 the external capacitor table. To
get an extremely low ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, which may produce a more
significant filtering effect. 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 (see figure 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 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.
