Pin Name

Pin Function

PGND

Power ground. Electrically needs to be connected to AGND.

2VIN

Supply voltage input. When VIN rises above the UVLO threshold the device starts up.

3AGND

Reference connection for controller section. Also used as thermal connection for controller section.

Electrically needs to be connected to PGND.

4FB

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

GND.

COMP

External loop compensation pin.

6EN

The enable pin is active HIGH. Connect it to VIN if not used and do not leave it open.

7, 8

PWM outputs connection to inductor.
