Texas Instruments · DC-DC Converters · TO-263-7
LM22676TJE-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, with a 10 nF bootstrap capacitor to BOOT; absolute maximum is -5 V to VIN. |
| 2 | VIN | power_in | Input supply to the regulator, operating range 4.5 V to 42 V with a 43 V absolute maximum. |
| 3 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side N-FET via a 10 nF capacitor to SW; absolute maximum is VSW + 7 V. |
| 4 | GND | power_in | Ground input to the regulator and system common. |
| 5 | NC | unconnected | Not electrically connected inside the chip, though the pin does function as a thermal conductor. |
| 6 | FB | input | Feedback input to the regulator; absolute maximum is -0.5 V to 7 V, and for the -5.0 option it connects to the 5 V output. |
| 7 | EN | input | Precision enable input that controls start-up and shutdown, with a 1.6 V (typ) falling threshold, about 6 µA internal pullup and a 6 V absolute maximum. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
