4) Place the overvoltage detection divider resistors as
5) Place IN pin bypass capacitor as close as possible
6) Minimize the size of the LX node while keeping it

close as possible to the OV pin. The divider’s cen-
ter trace should be kept short. Placing the resistors
far away causes the sensing trace to become
antennas that can pick up switching noise. Avoid
running the sensing traces near LX.

bypass capacitor should be connected directly to
GND pins with a wide trace.
wide and short. Keep the LX node away from the
feedback node and ground. If possible, avoid run-
ning the LX node from one side of the PCB to the
other. Use DC traces as shield if necessary.
