AOZ1282CI-1 from Alpha Omega Semicon, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	BST	passive	Bootstrap voltage input. High side driver supply. Connect a 100nF capacitor between BST and LX to develop the gate drive rail for the internal high-side NMOS.
2	GND	power_in	Ground reference for the device and internal analog circuitry.
3	FB	input	Feedback input. Regulated to 0.8V (typ). Set the output voltage with a resistor divider from VOUT to FB to GND. Feedback input current is typ 500nA.
4	EN	input	Enable pin, active high. On-threshold 1.2V typ, off-threshold 0.4V max, 200mV hysteresis. Connect to VIN through a current-limiting resistor; do not leave floating. Absolute max 40V.
5	VIN	power_in	Supply voltage input, 4.5V to 36V operating (40V absolute max). Device starts up when VIN rises above the UVLO threshold (~2.9V rising, 2.3V falling).
6	LX	power_out	PWM switching output. Drain of the internal 420mΩ NMOS power switch. Connect to the external inductor and freewheeling Schottky diode. Delivers up to 600mA continuous output current at 1MHz.
