Analog Devices Switching Regulators : To minimize output ripple in step-down DC/DC converters, can the output capacitor be placed closer to the IC than the input capacitor?

No, for a step-down DC/DC converter, the placement of the input capacitor is the most important, so try to place the input capacitor closest to the IC.

Regarding the reduction of output ripple, it is possible to reduce the ripple by using patterns and additional capacitors between the connection with loads such as microcomputers and FPGAs. If you would like to learn more, please join us at one of the seminars below.
