LM22671MRX-5.0 from Texas Instruments, in a SOIC-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 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side NFET; BOOT pin voltage is limited to VSW + 7 V. |
| 2 | SS | passive | Soft-start pin, where an external capacitor increases the soft-start time; SS pin voltage is limited to -0.5 V to 7 V. |
| 3 | RT/SYNC | input | Oscillator mode and frequency pin, used to set the switching frequency with a single resistor (200 kHz to 1 MHz) or to synchronize to a system clock; pin voltage is limited to -0.5 V to 7 V. |
| 4 | FB | input | Feedback input to the regulator; FB pin voltage is limited to -0.5 V to 7 V. |
| 5 | EN | input | Precision enable pin used to control regulator start-up, shut-down and UVLO; EN pin voltage is limited to -0.5 V to 6 V. |
| 6 | GND | power_in | System ground pin for the regulator. |
| 7 | VIN | power_in | Supply input to the regulator; recommended VIN supply range is 4.5 V to 42 V, with an absolute maximum VIN to GND of 43 V. |
| 8 | SW | output | Switching output of the regulator; SW to GND is limited to -5 V to VIN DC, with a -10 V extended limit for pulses up to 50 ns. |
