Efficient PCB layout is critical for stable

operation and thermal dissipation. For best

results, refer to Figure 5 and follow the

guidelines below.

1. Connect the IC’s OUT with short, direct,

and

wide

traces.

It

is

highly

recommended to add vias under the IC

and route the OUT trace on both PCB

layers.

2. Use a large copper plane for PGND.

Multiple vias should be added for better

thermal dissipation.

3. Connect AGND to PGND.

4. Use a large copper plane for SW and

USB.

5. Place the USB output capacitor close to

USB.

6. Place two ceramic input decoupling

capacitors as close to IN and PGND as

possible to improve EMI performance.

7. Place the VCC decoupling capacitor as

close to VCC as possible.

NOTE:

(8) The recommended layout is based on Figure 6: Typical

Application Circuit on the next page.
