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 power MOSFET gate driver. Connect a ≥0.1µF ceramic capacitor between BOOT and SW to develop the high-side gate drive voltage above the switching node. |+| 2 | VIN | power_in | Power supply input, 3.8V to 28V operating range (absolute max 34V). Must be locally bypassed with a low-ESR ceramic capacitor close to the pin. |+| 3 | EN | input | Enable logic input. Floating (internal pull-up) enables the device; can be tied directly to VIN (up to 34V absolute max). Precision UVLO thresholds: 1.18V rising / 1.1V falling for programmable UVLO via a resistor divider. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to ground per PCB layout convenience. |+| 5 | FB | input | Buck converter output feedback sensing input. Connect a resistor divider from VOUT to FB to program the output voltage; internal reference is 0.8V ±1% (0.792V-0.808V). Absolute max 5.5V. |+| 6 | NC | unconnected | No internal connection. Leave floating or tie to ground per PCB layout convenience. |+| 7 | NC | unconnected | No internal connection. Leave floating or tie to ground per PCB layout convenience. |+| 8 | SW | power_out | Switching node of the buck converter; junction of the internal high-side and low-side MOSFETs. Connect to the external inductor. Absolute max -0.3V to 34V. |+| 9 | GND | power_in | Exposed thermal pad - device ground return and primary heat dissipation path. Must be soldered to a PCB ground plane for proper electrical operation and thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SCT |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `SCT9336STERSTE`+- `SCT9336STERSTER`++## CAD (KiCad official)++- Symbol: `SCT9336STER`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SCT datasheet](docs/sct9336ster-datasheet.pdf) (20 pp, sha256 `4d5d86a19a2bc8e9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
