RT6254BHGJ6F from Richtek Tech, in a TSOT-23-6. 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 | FB | input | Feedback voltage input that sets the output voltage through an external resistive divider, with a reference of 0.6V (0.594V to 0.606V) and a feedback current of ±50nA. |
| 2 | EN | input | Enable control input that enables the device at logic high (VEN_H minimum 1.5V) and disables it at logic low (VEN_L maximum 0.4V); the absolute maximum rating is -0.3V to 20V. |
| 3 | GND | power_in | System ground that serves as the power return for the IC. |
| 4 | VIN | power_in | Power input that supplies the power switches, with a recommended operating range of 4.5V to 18V and an absolute maximum rating of -0.3V to 20V. |
| 5 | LX | output | Switch node that supplies power to the output LC filter, with an absolute maximum rating of -0.3V to 20V (-9V to 27V for less than 100ns). |
| 6 | BOOT | power_in | Bootstrap supply for the high-side gate driver, which requires a 0.1µF ceramic capacitor connected from LX to BOOT; the BOOT-to-LX voltage is limited to -3V to 9V for less than 100ns. |
