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. |
