Pin Function
Switch (Output): Internal power MOSFET output switches.
Enable (Input): Logic high enables operation of the regulator. Logic low will shut down the device. Do
not leave floating.
Sense: Connect to VOUT as close to output capacitor as possible to sense output voltage.
Analog Ground: Connect to central ground point where all high current paths meet (CIN, COUT, and
PGND) for best operation.
Input Voltage: Connect a capacitor-to-ground to decouple the noise.
Power Ground.
