2. Typical application
If not using our Mornsun’s EMC recommended circuit, please ensure an 100μF electrolytic capacitors in parallel with the input, which
used to suppress the surge voltage come from the input terminal.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the
product.
