2) Connect input and output capacitors to the power

ground plane; connect all other capacitors to the sig-

nal ground plane.

3) Keep the high-current paths as short and wide as

possible. Keep the path of switching current short

and minimize the loop area formed by LX, the output

capacitors, and the input capacitors.

4) Connect IN, LX, and PGND separately to a large

copper area to help cool the IC to further improve

efficiency and long-term reliability.

5) Ensure all feedback connections are short and

direct. Place the feedback resistors and compensa-

tion components as close to the IC as possible.

6) Route high-speed switching nodes away from sensi-

tive analog areas (FB, COMP).
