3) Place all feedback voltage-divider resistors as close
4) Place the INL pin and REF pin bypass capacitors as
5) Minimize the length and maximize the width of the
to their respective feedback pins as possible. The
divider’s center trace should be kept short. Placing
the resistors far away causes their FB traces to
become antennas that can pick up switching noise.
Care should be taken to avoid running any feedback
trace near LX1, LX2, DRVP, or DRVN.
close to the device as possible. The ground connec-
tion of the INL bypass capacitor should be connect-
ed directly to the GND pin with a wide trace.

nodes away from feedback nodes (FB1, FB2, FBP,
and FBN) and analog ground. Use DC traces as
shield if necessary.
