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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SCT |+| Package | TSOT-23-6L |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `SCT2331TVBR`++## CAD (KiCad official)++- Symbol: `SCT2331TVBR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: TSOT-23-6L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SCT datasheet](docs/sct2331tvbr-datasheet.pdf) (20 pp, sha256 `ba99a7b81262c402`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
