Design Reference

1. Typical application

All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) 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. capacitor load of the product.
