LM22676QTJE-ADJ
Texas Instruments · DC-DC Converters · TO-263-7
LM22676QTJE-ADJ 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, swinging from about zero volts to VIN, with the 10 nF bootstrap capacitor connected between SW and BOOT; absolute maximum -5 V to VIN (DC). |
| 2 | VIN | power_in | Input supply to the regulator, operating range 4.5 V to 42 V (absolute maximum 43 V). |
| 3 | BOOT | input | Bootstrap input providing the gate voltage for the high-side N-FET via a 10 nF capacitor to SW; absolute maximum VSW + 7 V. |
| 4 | GND | power_in | System ground pin and ground input to the regulator. |
| 5 | NC | unconnected | Not electrically connected inside the chip, but the pin functions as a thermal conductor. |
| 6 | FB | input | Feedback input to the regulator, regulated to 1.285 V (typ) on the ADJ version via an external divider; absolute maximum -0.5 V to 7 V. |
| 7 | EN | input | Precision enable input controlling start-up and shutdown, with a 1.6 V (typ) falling threshold, 0.6 V hysteresis and about 6 uA internal pullup; must not exceed 6 V. |
| 8 | EP | power_in | Exposed pad, connect to ground to provide the thermal connection to the PCB. |
