LM22679TJE-5.0 from Texas Instruments, in a TO-263-7. 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 absolute maximum SW-to-GND rating is -5 V DC up to VIN, with a -10 V limit for pulses of up to 50 ns. |
| 2 | VIN | power_in | Supply input to the regulator; the recommended VIN range is 4.5 V to 42 V, and the absolute maximum VIN-to-GND rating is 43 V. |
| 3 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side NFET; the absolute maximum boot pin voltage is VSW + 7 V. |
| 4 | GND | power_in | Ground input to the regulator and system common; connect to the system ground. |
| 5 | IADJ | input | Current-limit adjust input; a resistor between this pin and GND sets the current-limit threshold, the pin can be left floating for the internal default, and the absolute maximum pin voltage is -0.5 V to 7 V. |
| 6 | FB | input | Feedback input to the regulator; the absolute maximum FB pin voltage is -0.5 V to 7 V. |
| 7 | SS | output | Soft-start pin used to increase the soft-start time (see section 7.3.2); the absolute maximum SS pin voltage is -0.5 V to 7 V. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
