LM3224MMX-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 | output | Compensation network connection to the output of the voltage error amplifier. |
| 2 | FB | input | Output voltage feedback input. |
| 3 | SHDN | input | Shutdown control input, active low, with internal pulldown resistor; device enables when pulled high. |
| 4 | GND | power_in | Analog and power ground. |
| 5 | SW | output | Power switch output; switch connected between SW and GND pins. |
| 6 | VIN | power_in | Analog power supply input. |
| 7 | FSLCT | input | Switching frequency select input; 1.25MHz when connected to VIN or 615kHz when connected to GND. |
| 8 | SS | input | Soft-start control pin. |
