SCT2331TVBR 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 | FB | input | Buck converter output feedback sensing voltage. Connect a resistor divider from VOUT to FB to set the output voltage. The device regulates FB to the internal 0.8V (typ, ±1%) reference. |
| 2 | EN | input | Enable logic input. Floating the pin enables the device. Supports high-voltage input up to VIN (max 34V abs). Precision enable thresholds 1.18V rising / 1.1V falling for programmable UVLO with hysteresis. |
| 3 | VIN | power_in | Power supply input, 3.8V to 32V operating (abs max 34V). Must be locally bypassed with a ceramic capacitor close to the pin. |
| 4 | GND | power_in | Power ground. Must be soldered directly to the PCB ground plane for proper thermal performance and return current. |
| 5 | SW | output | Switching node of the buck converter. Connect to the external inductor. Abs max -0.3V to 34V. Delivers up to 3A continuous. |
| 6 | BST | power_in | Bootstrap: power supply for the high-side power MOSFET gate driver. Connect a 0.1µF or greater ceramic capacitor between BST and SW. Abs max -0.3V to 40V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 527 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.
