Note B1: It is important to have a direct, low-impedance return path for high current back to the power supply. Keep
impedance low from top to bottom side of PCB through a lot of ground vias.
Note B2: Bootstrap low-impedance X7R ceramic capacitors placed on bottom side provide a short low-inductance
current loop.
Note B3: Return currents from bulk capacitors and output filter capacitors
