VID<0:4>, AF_EN, PGOOD, and VR_ON
These are logic signals that do not require special attention.
FDE
This logic signal should be treated as noise sensitive and
should be routed away from rapidly rising voltage nodes,
(switching nodes) and other noisy traces.
VIN
The VIN signal should be connected near the drain of the
high-side MOSFET.
Copper Size for the Phase Node
The parasitic capacitance and parasitic inductance of the
phase node should be kept very low to minimize ringing. It is
best to limit the size of the PHASE node copper in strict
accordance with the current and thermal management of the
application. An MLCC should be connected directly across
the drain of the high-side MOSFET and the source of the
low-side MOSFET to suppress turn-off voltage spikes.
