LM22672QMRX-ADJ 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 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side NFET. |
| 2 | SS | input | Soft-start input; a capacitor on this pin is used to increase the soft-start time. |
| 3 | RT/SYNC | input | Oscillator mode control input used to set the switching frequency or synchronize the oscillator to a system clock (see Frequency Adjustment and Synchronization section). |
| 4 | FB | input | Feedback input to the regulator. |
| 5 | EN | input | Enable input that controls regulator start-up and shutdown (see Precision Enable and UVLO section). |
| 6 | GND | power_in | System ground pin of the regulator (system common). |
| 7 | VIN | power_in | Supply input to the regulator; recommended VIN supply range is 4.5 V to 42 V and the VIN-to-GND absolute maximum is 43 V. |
| 8 | SW | output | Switching output of the regulator; SW to GND DC absolute maximum is -5 V to VIN, with a -10 V limit for pulses up to 50 ns. |
