Short and wide traces must be implemented for main current and for power ground paths.

The input capacitor must be placed as closer as possible to the device pins as well as the

inductor and output capacitor.

The feedback pin (FB) is a high impedance node, so the interference can be minimized by

placing the routing of the feedback node as far as possible from the high current paths. A

common ground node minimizes ground noise.
