VIN

Supply voltage input. When VIN rises above the UVLO threshold the

device starts up.

AGND

Reference connection for controller section. Also used as thermal

connection for controller section. Electrically needs to be connected

to PGND.

FB

The FB pin is used to determine the output voltage via a resistor

divider between the output and GND.

EN

The enable pin is active high. Connect it to VIN if not used and do

not leave it open.
