SCT2231TVBR from SCT, in a TSOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power ground. Must be soldered directly to the ground plane for proper thermal and electrical performance. |
| 2 | SW | power_out | Power switching output. Switching node connecting the internal high-side and low-side MOSFETs. Connect an external LC output filter from SW to the load. Absolute max -1V to 20V (transient -2.5V to 22V for <10ns). |
| 3 | VIN | power_in | Power supply input, 4.2V to 17V. Supplies the IC and the step-down converter switches. Bypass to GND with a suitably large ceramic capacitor close to the pin to eliminate input noise. |
| 4 | FB | input | Buck converter output feedback sensing input. Connect a resistor divider from VOUT to FB to program the output voltage. The device regulates FB to the internal 0.8V (typ) reference. |
| 5 | EN | input | Enable logic input. Floating the pin enables the device. Precision enable thresholds: 1.2V rising / 1.1V falling for programmable UVLO threshold and hysteresis. Input current typ 1.5µA at EN=1V; hysteresis current typ 5.5µA at EN=1.5V. |
| 6 | BST | power_in | Bootstrap supply for the high-side power MOSFET gate driver. Connect a 0.1µF or greater ceramic capacitor between BST and SW. Absolute max VSW-0.3V to VSW+6V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 511 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
