Texas Instruments · DC-DC Converters · TO-263-7
LM22676QTJ-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; the bootstrap capacitor connects between SW and BOOT, and its absolute maximum is -5 V to VIN (DC). |
| 2 | VIN | power_in | Input supply to the regulator, operating range 4.5 V to 42 V (43 V absolute maximum). |
| 3 | BOOT | input | Bootstrap input that provides the gate voltage for the high-side N-FET; a 10 nF ceramic capacitor is connected from BOOT to SW (VSW + 7 V maximum). |
| 4 | GND | power_in | Ground input to the regulator and system common. |
| 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; 1.285 V typical reference on the ADJ version, connected to an external resistor divider (FB absolute maximum 7 V). |
| 7 | EN | input | Precision enable input that controls regulator start-up and shutdown; threshold is 1.6 V typ falling with 0.6 V hysteresis and about 6 µA internal pullup (6 V absolute maximum). |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
