trace should be kept short. Placing the resistors far
away causes the FB trace to become an antenna
that can pick up switching noise. Avoid running the
feedback trace near LX.

IN bypass capacitor should be connected directly
to AGND pins with a wide trace.

feedback node and analog ground. Use DC traces
as a shield if necessary.
