LM3224MM-ADJ from Texas Instruments, in a MSOP-8. 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 | input | Compensation network connection connected to the voltage error amplifier output; absolute maximum voltage 1.26V ± 0.3V. |
| 2 | FB | input | Output voltage feedback input with reference voltage 1.2285V to 1.2915V and absolute maximum voltage 7V (must not exceed VIN). |
| 3 | SHDN | input | Shutdown control input, active low, with internal pulldown resistor; must be pulled high to enable device; voltage range 0V to 7.5V. |
| 4 | GND | power_in | Analog and power ground reference. |
| 5 | SW | output | Power switch node connected between internal NMOS switch and external inductor; absolute maximum voltage 21V with switch current limit 1.9A to 2.8A. |
| 6 | VIN | power_in | Analog power input; operating voltage range 2.7V to 7V with absolute maximum 7.5V. |
| 7 | FSLCT | input | Switching frequency select input; VIN level selects 1.25MHz operation, GND level selects 615kHz operation; voltage range 0V to 7.5V. |
| 8 | SS | input | Soft-start control pin charged by internal current source 7.5µA to 13µA to limit startup inrush current; optional pin can be left open if not needed. |
