The printed-circuit-board (PCB) layout is an important step to maintain the high performance of the device. See Figure 8-28 for the recommended PCB layout.

• The input/output capacitors and the inductor must be placed as close as possible to the IC. This keeps the power traces short. Routing these power traces direct and wide results in low trace resistance and low parasitic inductance.
• The low side of the input and output capacitors must be connected properly to the GND pin to avoid a ground potential shift.
• The sense traces connected to FB is a signal trace. Special care must be taken to avoid noise being induced. Keep these traces away from SW nodes. The connection of the output voltage trace for the FB resistors must be made at the output capacitor.
• Refer to Figure 8-28 for an example of component placement, routing and thermal design.
