Layout Considerations
When laying out a board, minimize trace lengths be-
tween the IC and the inductor, diode, input capacitor,
output capacitor, and R1. Keep traces short, direct, and
wide. Keep noisy traces, such as the SW node trace,
away from FB. Place the VIN bypass capacitor(C1) as
close to the IC as possible. The ground connections of
C1 and C2 should be as close together as possible. Star
connect the grounds for R2, R3, C3, and the CTRL volt-
age supply as close to the IC as possible.
