Pin Function
Supply voltage input. When VIN rises above the UVLO threshold the device starts up.
Power ground. Electrically needs to be connected to AGND.
Reference connection for controller section. Also used as thermal connection for controller
section. Electrically needs to be connected to PGND.
The FB pin is used to determine the output voltage via a resistor divider between the output and
GND.
External loop compensation pin.
The enable pin is active HIGH. Connect EN pin to VIN if not used. Do not leave the EN pin floating.
PWM output connection to inductor. Thermal connection for output stage.
