Layout Considerations for High-Power CircuitsTutorial
Board layout should be considered from the very beginning of a design. The most important rule for high power circuit boards is to know your power path. The location and amount of power flowing through a circuit is a major factor when deciding the IC position and type and amount of heat dissipation required on the printed circuit board (PCB).
