As for all switching power supplies, the layout is an important step in the design, especially at high peak currents and high switching frequencies. If the layout is not carefully done, the regulators could show stability problems as well as EMI problems. Therefore, use wide and short traces for the main current path and for the power ground tracks. Input capacitors, output capacitors, and inductors should be placed as close as possible to the IC.
