8.1 Layout Guidelines

The layout is an important step in the design process. Proper function of the device demands careful attention to the PCB layout. Care must be taken in board layout to get the specified performance. If the layout is not carefully done, the regulators may show poor performance including stability issues as well as EMI problems. It is critical to provide a low impedance ground path. Therefore, use wide and short traces for the main current paths. The input capacitors must be placed as close as possible to the IC pins as well as the inductor and output capacitor.

Keep the common path to the ground pins which return the small signal components and the high current of the output capacitors as short as possible in order to avoid ground noise.
