LAYOUT RECOMMENDATION

1. Place high current paths (GND, IN, and SW)

very close to the device with short, direct and

wide traces.

2. Put a decoupling capacitor as close to the

VCC and AGND pins as possible.

3. Keep the switching node (SW) plane as small

as possible and far away from the feedback

network.

4. Place the external feedback resistors next to

the FB pin. Make sure that there are no vias

on the FB trace. The feedback resistors

should refer to AGND instead of PGND.

5. Keep the BST voltage path (BST, C3, and

SW) as short as possible.

6. Recommend strongly a four-layer layout to

improve thermal performance.
