PCB Layout Guidelines

(6)

Efficient PCB layout is critical for stable

operation. For best results, refer to Figure 7 and

follow the guidelines below.

1. Keep the connection of the input ground

and GND as short and wide as possible.

2. Keep the connection of the input capacitor

and IN as short and wide as possible.

3. Ensure that all feedback connections are

short and direct.

4. Place

the

feedback

resistors

and

compensation components as close to the

chip as possible.

5. Route SW away from sensitive analog

areas such as FB.

NOTE:

6)

The recommended layout is based on Figure 8: Typical

Application Circuit on page 14.
