If you want to further decrease the input/output
ripple, you can increase capacitance properly or
choose capacitors with low ESR. 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). General:

APPLICATION NOTE
Requirement Output Load
In order to ensure the product operate efficiently and reliably, in addition to a max load (namely
full load), a minimum load is specified for this kind of DC/DC converter. Make sure the specified
range of input voltage is not exceeded, the minimum output load no less than 10% load. If the
actual load is less than the specified minimum load, the output ripple may increase sharply while
its efficiency and reliability will reduce greatly. If the actual output power is very small, please add
an appropriate resistor as extra loading, or contact our company for other lower output power
products.
