LM22676QMR-5.0 from Texas Instruments, in a SO-8. 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 | SW | output | Switching output of the regulator; the SW to GND DC limit is -5 V to VIN, with a -10 V extended limit for pulses up to 50 ns. |
| 2 | VIN | power_in | Input supply to the regulator, with VIN to GND rated at 43 V absolute maximum and a recommended supply range of 4.5 V to 42 V. |
| 3 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side N-FET; BOOT pin voltage is limited to VSW + 7 V. |
| 4 | GND | power_in | System ground pin serving as the common ground for the regulator. |
| 5 | NC | unconnected | Not connected inside the chip; the pin functions as a thermal conductor. |
| 6 | FB | input | Feedback input to the regulator; FB pin voltage is limited to -0.5 V to 7 V. |
| 7 | EN | input | Precision enable input used to control regulator start-up and shutdown; EN pin voltage is limited to -0.5 V to 6 V. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
