AX5201

Layout Guidance (please refer layout picture)

When laying out the PC board, the following suggestions should be taken to ensure

proper operation of the AX5201. These items are also illustrated graphically in below.

1. The power traces, including the Source trace, the Schottky and the C1 trace should be

kept short, direct and wide to allow large current flow.

2. The power ground is keep C4’s ground closed and far away signal ground.

3. The signal ground trance is distant from power ground trance.

4. The exposed pad is connecting to SW trace closely and widely. (Reduce IC

temperature)

5. Do not trace signal line under inductor.
