Pin Function
Power ground. Electrically needs to be connected to AGND.
Supply voltage input. When VIN rises above the UVLO threshold the
device starts up.
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 it to VIN if not used and do
not leave it open.
PWM output connection to inductor.
No Connect. Pin 7 and 8 are not internally connected. Connect
these two pins externally to LX and use them for better thermal
performance.
