**Texas Instruments** · Global Sourcing Parts · VSSOP-8-0.65mm

LM2622MMX-ADJ from Texas Instruments, in a VSSOP-8-0.65mm. 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 | VC | passive | Compensation network connection, connected to the output of the voltage error amplifier. |
| 2 | FB | input | Output voltage feedback input. |
| 3 | SHDN | input | Shutdown control input, active low. |
| 4 | GND | power_in | Analog and power ground. |
| 5 | SW | input | Power switch input; the internal switch is connected between the SW pin and the GND pin. |
| 6 | VIN | power_in | Analog power input. |
| 7 | FSLCT | input | Switching frequency select input: VIN selects 1.3MHz and ground selects 600kHz. |
| 8 | NC | unconnected | Connect to ground or leave open; connect directly to the GND pin beneath the device if possible, otherwise leave open and shield from EMI. |
