LM22676TJ-ADJ from Texas Instruments, in a TO-263-7. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switching output of the regulator connected to the drain of the internal N-channel power MOSFET, rated from -5 V to VIN under normal operation (with an extended -10 V transient limit allowed for pulses up to 50 ns). |
| 2 | VIN | power_in | Input supply voltage to the regulator, with a recommended operating range of 4.5 V to 42 V and an absolute maximum rating of 43 V to GND. |
| 3 | BOOT | input | Bootstrap input that provides the gate drive voltage for the internal high-side N-channel MOSFET via an external capacitor to SW, with an absolute maximum rating of VSW + 7 V. |
| 4 | GND | power_in | Ground input to the regulator; system common/ground pin. |
| 5 | NC | unconnected | Not internally connected pin; it is electrically isolated inside the chip and functions only as a thermal conductor. |
| 6 | FB | input | Feedback input to the regulator's internal error amplifier, regulated to 1.285 V (typ) for the ADJ option, with an absolute maximum voltage rating of -0.5 V to 7 V. |
| 7 | EN | input | Precision enable input used to control regulator start-up and shutdown, with a falling enable threshold of 1.6 V (typ) and an absolute maximum voltage rating of -0.5 V to 6 V. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
