Arrange the components so that the switching current loops curl in the same direction. Due to the way switching

regulators operate, there are two power states. One state when the switch is ON and one when the switch is

OFF. During each state there is a current loop made by the power components that are currently conducting.

Place the power components so that during each of the two states the current loop is conducting in the same

direction. This prevents magnetic field reversal caused by the traces between the two half-cycles and reduces

radiated EMI.
