Place all feedback voltage-divider resistors as
close to their respective feedback pins as possible.
The divider’s center trace should be kept short.
Placing the resistors far away causes their FB
traces to become antennas that can pick up switch-
ing noise. Care should be taken to avoid running
any feedback trace near LX1, LX2, DRVP, or DRVN.
Place V
tors as close to the device as possible. The ground
connection of the VL bypass capacitor should be
connected directly to the GND pin with a wide trace.

Refer to the MAX17014 evaluation kit for an example of
proper board layout.
Minimize the length and maximize the width of the
traces between the output capacitors and the load
for best transient responses.
Minimize the size of the LX1 and LX2 nodes while
keeping them wide and short. Keep the LX1 and
LX2 nodes away from feedback nodes (FB1, FB2,
FBP, and FBN) and analog ground. Use DC traces
as a shield, if necessary.
