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 | VFB | input | LED drive current setting terminal. Connect an external resistor RFB between this pin and GND to program the constant output current: ILED = VFB / RFB, with VFB typically 150 mV (144-156 mV). Absolute max voltage -0.3 V to 5.5 V. |+| 2 | GND | power_in | Ground reference for the device. RFB feedback resistor returns to this pin. |+| 3 | DIM | input | PWM dimming control input with built-in 50 kΩ pull-up resistor to internal 5 V rail; may be left floating if dimming is not required (chip outputs maximum current). Logic levels: VIH >= 2.5 V, VIL <= 0.4 V. Absolute max voltage -0.3 V to 5.5 V. |+| 4 | VCC | power_in | Power supply input, 2.5 V to 24 V operating range (absolute max -30 V to 28 V). Features reverse-connection protection, with reverse leakage current below 10 uA at VCC = -30 V. For VCC >= 12 V direct-supply applications, a 1 kΩ series resistor is recommended to suppress hot-swap transients. |+| 5 | DRV | output | LED drive sink current output. Connects to the cathode of the LED string; sinks up to 200 mA continuous with a saturation drop of only ~175 mV. Absolute max voltage -0.3 V to 32 V. Leakage current below 1 uA when disabled. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Cross chip |+| Package | SOT-23-5 |+| Category | LED-drv |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `CC1108ST`++## CAD (KiCad official)++- Symbol: `CC1108ST`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Cross chip datasheet](docs/cc1108st-datasheet.pdf) (10 pp, sha256 `f4fa14d08e0968f2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
