Due to fast switching waveforms and high-current
paths, careful PC board layout is required. An evalua-
tion kit (MAX8596XEVKIT) is available to speed design.
When laying out a board, minimize trace lengths
between the IC and R
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 IN bypass
capacitor (C

inductor and from the Schottky diode to the LEDs can
