CSN1
Negative Input of the Output Current Sense of Phase 1. This pin should be connected to the
negative side of the output current-sensing resistor or the filtering capacitor if the DC resistance of
the output inductor is utilized for current sensing. A 10
discharge FET is turned on in UVLO event
or thermal shutdown, or at the end of soft-shutdown.

PAD (GND)
Exposed Backplate (Pad) of Package. Internally connected to both analog ground and power
(driver) grounds. Connect to the ground plane through a thermally enhanced via.
