Pin Function

VIN

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

PGND

Power ground. Electrically needs to be connected to AGND.

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.

COMP

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.

7, 8

PWM output connection to inductor. Thermal connection for output stage.
