SLES221C – JULY 2009 – REVISED APRIL 2010

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
