RT6212AHGJ6F from Richtek Tech, in a TSOT-23-6L. 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 | GND | power_in | System ground providing the ground return path for the control circuitry and low-side power MOSFET. |
| 2 | LX | passive | Switch node that supplies power to the output and connects the output LC filter from LX to the output load. |
| 3 | VIN | power_in | Power input supplying the power switches of the device, 4.5V to 18V operating range. |
| 4 | FB | input | Feedback voltage input used to set the output voltage via an external resistive divider; feedback voltage is 0.8V typical for the RT6212AHGJ6F. |
| 5 | EN | input | Enable control input; floating or connecting to GND disables the device and logic high enables it (rising threshold 1.5V typical for the HGJ6F version). |
| 6 | BOOT | passive | Bootstrap supply for the high-side gate driver; connect a 100nF or greater capacitor from LX to BOOT. |
