Pin Description (continued)
PIN NAME FUNCTION
40 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.
