... NMOS switch is ON, and one when the NMOS switch is OFF. During each state there will be a current loop made by the power components that are conducting. The input and output capacitors must be arranged in such a way on the SSL3252 that during each of the two states the current loop is conducting in the same direction. This prevents phase reversal of the magnetic field, and reduces radiated EMI ...

... Priority should be given for the output capacitor to be positioned as close as possible to the VO and PGND nodes of the SSL3252. Since large currents will flow from input capacitor to the inductor and not to the VIN pin of the SSL3252 wise to locate the input capacitor near the inductor. The VIN pin should be star-connected to the positive pad of the input capacitor ...
