LM22672MRX-5.0 from Texas Instruments, in a SOIC-8-EP. 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 gate voltage for the high-side NFET with absolute maximum rating of VSW + 7 V. |
| 2 | SS | input | Soft-start input used to extend regulator soft-start time via external capacitor with voltage range of -0.5 to 7 V. |
| 3 | RT/SYNC | input | Oscillator control input for setting switching frequency or enabling external synchronization with voltage range of -0.5 to 7 V. |
| 4 | FB | input | Feedback input to error amplifier for closed-loop output voltage regulation with voltage range of -0.5 to 7 V. |
| 5 | EN | input | Precision enable input with built-in UVLO function to control regulator start-up and shutdown with voltage range of -0.5 to 6 V. |
| 6 | GND | power_in | System ground reference pin that serves as the return path for input supply and circuit common. |
| 7 | VIN | power_in | Input supply voltage to regulator with recommended operating range of 4.5 to 42 V. |
| 8 | SW | output | High-frequency switching output with voltage range of -5 to VIN V (dc), with transient limit of -10 V for pulses up to 50 ns. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
