Function
Input Voltage for Control Circuitry.
Enable.
Low noise ground.
Soft-Start Pin.
No Connect. This pin must be tied to ground.
Input Voltage for Power Circuitry.
Switch Pin.
Power Ground.
No-Connect. These pins must be tied to ground.
Output Voltage Sense Pin.
The exposed pad is internally connected to GND, but it cannot be
used as the primary GND connection. The exposed pad should be
soldered to an external GND plane.
