Sensitive signals should be routed on different layers or
some distance away from the PHASE plane on the same
layer. Crosstalk due to switching noise is reduced into these
lines by isolating the routing path away from the PHASE
plane. Layout the PHASE planes on one layer, usually the
top or bottom layer, and route the voltage feedback traces on
another remaining layer.

Thermal Management
For maximum thermal performance in high current, high
switching frequency applications, connecting the thermal
PGND pad of the ISL65426 to the ground plane with multiple
vias is recommended. This heat spreading allows the IC to
achieve its full thermal potential. If possible, place the
controller in a direct path of any available airflow to improve
thermal performance.
