Name and function
Analog input supply voltage to be tied to VIN supply source
Inhibit pin active low. Connect to VIN_A if not used
Feedback voltage for connection to external voltage divider to set the VOUT
from 0.8V up to 0.85*VIN_SW. (see output voltage selection paragraph 5.5)
Analog ground
Synchronization and frequency select. Connect SYNC to GND for 900 kHz
operation, or to an external clock from 400 kHz to 1.2 MHz. (see Sync
operation paragraph 5.8.1)
Power input supply voltage to be tied to VIN power supply source
Switching node to be connected to the inductor
Power ground
Exposed pad to be connected to ground
