Abstract
A highly efficient, multi-layered, single component sided circuit board layout design providing reduced parasitic inductance for power switched circuits. Mounted on the top board are one or more transistor switches, one or more loads, and one or more capacitors. The switches and capacitors form a loop with very low parasitic inductance. The loads may be a part of the loop, i.e. in series with the switches and capacitors, or may be connected to two or more nodes of the loop to form additional loops with common vertices. Parallel wide conductors carry the switch load current resulting in a low inductance path for the power loop. The power loop and gate loop current travel in opposite directions and are well separated, minimizing common source inductance (CSI) and maximizing switching speed.
