... Basic design rules include: (1) maintaining wide traces for power components (e.g., width > 50mils); (2) place C diode, and the inductor close to the LX1910; (3) minimizing trace capacitance by reducing the etch area connecting the SW pin to the inductor; and (4) minimizing the etch length to ...
