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 | BOOT | passive | Bootstrap supply for the high-side MOSFET gate driver. Connect a 0.1 µF (or greater) ceramic capacitor between BOOT and SW; the cap is refreshed when the low-side FET turns on. |+| 2 | VIN | power_in | Power supply input, 3.8 V to 32 V. Must be locally bypassed with a low-ESR ceramic capacitor placed close to the pin. |+| 3 | EN | input | Enable logic input. Floating the pin enables the device; can be tied directly to VIN (rated up to 34 V). Precision enable thresholds: 1.18 V rising / 1.1 V falling for programmable UVLO with hysteresis. |+| 4 | NC | unconnected | Not connected. Leave floating or tie to a copper island for thermal relief; no internal connection. |+| 5 | FB | input | Buck converter output feedback sensing input. Connect a resistor divider from VOUT to FB to set the output voltage; the internal reference regulates FB to 0.8 V typical (0.792 V-0.808 V). |+| 6 | NC | unconnected | Not connected. Leave floating or tie to a copper island for thermal relief; no internal connection. |+| 7 | GND | power_in | Power ground return for the low-side MOSFET and controller. Must be soldered directly to the ground plane with a low-impedance connection. |+| 8 | SW | power_out | Switching node of the buck converter. Connect to the output inductor and to the BOOT capacitor. High dV/dt node; keep trace short and shielded to minimize EMI. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SCT |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `SCT9320STDRSTD`+- `SCT9320STDRSTDR`++## CAD (KiCad official)++- Symbol: `SCT9320STDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SCT datasheet](docs/sct9320stdr-datasheet.pdf) (20 pp, sha256 `3cd46ac0287aaae0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
