LM22670TJE-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 DC voltage SW-to-GND is limited to -5 V through VIN, with a -10 V limit for pulses up to 50 ns. |
| 2 | VIN | power_in | Supply input to the regulator, recommended for 4.5 V to 42 V, with an absolute maximum VIN-to-GND of 43 V. |
| 3 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side NFET; BOOT pin voltage is limited to VSW + 7 V. |
| 4 | GND | power_in | Ground input to the regulator and the system ground pin. |
| 5 | RT/SYNC | input | Switching frequency adjustment and synchronization input used to control the oscillator mode; pin voltage is limited to -0.5 V to 7 V. |
| 6 | FB | input | Feedback input to the regulator; pin voltage is limited to -0.5 V to 7 V. |
| 7 | EN | input | Precision enable input that controls regulator start-up, shut-down and UVLO; 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). |
