U Minimize the length and maximize the width of the
traces between the output capacitors and the load for
best transient responses.
U 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,
FBN, and VREF_FB) and analog ground. Use DC
traces as shield if necessary.
Refer to the MAX17126 evaluation kit for an example of
proper board layout.
