ISENSE FEEDBACK
The screen grab below shows the current sense connections for inductior current sensing, on layers 1 and 3,
from the output inductor to pins 45 and 46 on the IRPS5401.

VSENSE FEEDBACK
In this screen grab the VSENSE lines on layer 3 are highlighted. The DB295 has a divider network and a 10 Ω
resistor for small signal injection to do Bode Plots. An actual layout could be simpler if the divider network is
not required.
