Pin Function

PWM output connection to inductor. Thermal connection for output stage. 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. Not connected External loop compensation pin. The enable pin is active high. Do not leave it open. Power ground. Electrically needs to be connected to AGND. Power Good. Open drain. Use resistor to pull up to 5V supply. Low side MOSFET driver Connect it to the gate of external low side MOSFET.
