**Torex Semicon** · DC-DC Converters · SOT-89-3

XC6372A331PR-G from Torex Semicon, in a SOT-89-3. 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 | VSS | power_in | Ground pin for the converter; the datasheet lists it only as the ground connection with no voltage limit given for this pin. |
| 2 | VOUT | power_out | Output voltage monitor and IC internal power supply; the absolute maximum VOUT input voltage is 12 V. |
| 3 | Lx | output | Switch pin driving the inductor through the built-in switching transistor; absolute maximum LX pin voltage is 12 V and LX pin current is 400 mA. |
