Locate the output inductors and output capacitors between
the MOSFETs and the load. Route high-speed switching
nodes away from sensitive analog areas (ISP, ISN, FB,
FBRTN, COMP, ADJ, OFS, IMAX.....)
Keep the routing of the bootstrap capacitor short between
BOOT and PHASE.
Place the snubber R&C as close as possible to the lower
MOSFETs of each phase.
