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.

PWM output connection to inductor.

Power good signal output pin. It is an open drain output used to indicate the status of output

voltages. This pin is internally pulled low when the output is below 90% of the nominal voltage.
