•

Avoid vias as much as possible. If vias are used, use mul-

tiple vias in parallel and/or make them as large as pos-

sible.

•

Place the output capacitor and ferrite beads as close to

the USB connector as possible.

•

If ferrite beads are used, use wires with minimum resis-

tance and large solder pads to minimize connection re-

sistance.
