LAYOUT GUIDELINES
Place the compensator components in general proximity of the controller
Each ISEN pin has a capacitor (Cisen) decoupling it to VSUMN, then through another capacitor (Cvsumn) to GND. Place
ISEN2, ISEN1 Cisen capacitors as close as possible to the controller and keep the following loops small:
1. Any ISEN pin to another ISEN pin
2. Any ISEN pin to GND
The red traces in the following drawing show the loops that need to minimized.

Place the VSEN/RTN filter in close proximity of the controller for good decoupling. Route these signals differentially
from the remote sense location back to the controller.
Place the current sensing circuit in general proximity of the controller.
Place capacitor Cn very close to the controller.
Place the NTC thermistor next to the phase 1 inductor so it senses the inductor temperature correctly.
Each phase of the power stage sends a pair of VSUMP and VSUMN signals to the controller. Run these two signals traces
in parallel fashion.
IMPORTANT: Sense the inductor current by routing the sensing circuit to the inductor pads. If possible, route the traces
on a different layer from the inductor pad layer and use vias to connect the traces to the center of the pads. If no via is
allowed on the pad, consider routing the traces into the pads from the inside of the inductor. The following drawings
show the two preferred ways of routing current sensing traces. If possible connect the traces to the inductor pad in only
one place and isolate this connection from other planes of the same net that may be present on other layers. Also make
the connections a symmetric as possible for all phases.
