close as possible to the IC, and avoiding the use of

vias if possible. The inductor, input filter capacitor, and

output filter capacitor should be connected as close

together as possible, with short, direct, and wide

traces. The ground nodes for each regulator’s power

loop should be connected at a single point in a star-

ground configuration, and this point should be

connected to the backside ground plane with multiple

vias. The output node for each regulator should be

connected to its corresponding OUTx pin through the

shortest possible route, while keeping sufficient

distance from switching nodes to prevent noise

injection. Finally, the exposed pad should be directly

connected to the backside ground plane using multiple

vias to achieve low electrical and thermal resistance.
