Typical application

All the DC/DC converters of this series are tested according to the

recommended circuit (see Fig. 1) before delivery.

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.
