When laying out a board, minimize trace lengths
between the IC and RSENSE, the inductor, the diode,
the input capacitor, and the output capacitor. Keep
traces short, direct, and wide. Keep noisy traces, such
as the LX node trace, away from CS. The input bypass
capacitor (CIN) should be placed as close to the IC as
possible. For the thin QFN package, PGND and GND
should be connected directly to the exposed paddle
underneath the IC. The ground connections of CIN and
COUT1 should be as close together as possible. The
traces from IN to the inductor and from the Schottky
diode to the LEDs can be longer.
