RT8082GQW from Richtek Tech, in a WDFN-12-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LX | output | Internal power MOSFET switch output; connect to the inductor (pin 12 is also LX and the two must be tied together). |
| 2 | VIN | power_in | Power input; decouple to GND with two 10µF capacitors (pin 11 is also VIN). |
| 3 | PGND | power_in | Power ground; the exposed pad (pin 13) must be soldered to a large PCB and connected to ground for maximum power dissipation. |
| 4 | AGND | power_in | Analog ground providing the return path for the control circuit and internal reference. |
| 5 | BIAS | power_in | Analog power input; decouple to AGND with a minimum 0.1µF ceramic capacitor. |
| 6 | FB | input | Feedback input that sets the output voltage through an external resistive divider; feedback reference is 1V typical. |
| 7 | NC | unconnected | No internal connection. |
| 8 | EN | input | Enable control input; floating or driving logic high enables the device, and driving logic low disables it. |
| 9 | PGOOD | output | Open-drain power good indicator, pulled to ground when the output voltage is within 7% of the regulation point; requires an external pull-up. |
| 10 | PGND | power_in | Power ground, one of the PGND pins (3, 10, 13) of the device. |
| 11 | VIN | power_in | Power input; decouple to GND with two 10µF capacitors (pin 2 is also VIN). |
| 12 | LX | output | Internal power MOSFET switch output; connect to the inductor together with pin 1. |
| 13 | PGND | power_in | Exposed pad, power ground; must be soldered to a large PCB and connected to ground for maximum power dissipation. |
