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 | SW | output | Power switch node: drain of the integrated NMOS. Connects to the boost inductor and Schottky rectifier. Rated -0.3V to 35V absolute max; NMOS RDS(on) ≈ 0.2Ω; peak current limit 1.2-1.4A. |+| 2 | GND | power_in | Device ground. Should be tied to a strong ground plane for heat sinking and noise protection. |+| 3 | FB | input | Output voltage / LED current feedback pin. Regulated to 202mV (196-208mV) when EN/PWM is high; the LED current is set by the sense resistor R1 as ILED = 202mV / R1. |+| 4 | EN/PWM | input | Chip enable and PWM dimming input. Drive above 1.5V to turn on, below 0.4V to turn off. A PWM signal (recommended ≥1kHz or ≤200Hz) scales the effective 202mV reference by its duty cycle for LED brightness control. Do not leave floating. Absolute max 25V; leakage ±1µA. |+| 5 | OVP | input | Over-voltage sense input for open-LED protection. Connect to the top of the LED string / boost output. Switching stops when OVP rises above ~30V and resumes when it falls below ~25V. Absolute max -0.3V to 35V. |+| 6 | IN | power_in | Power supply input, 2.5V to 7V (absolute max 8V). Must be decoupled to GND with a ≥1µF ceramic capacitor placed close to the pin. UVLO threshold ≈ 2.4V with 100mV hysteresis. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TMI |+| Package | SOT-23-6 |+| Category | LED-drv |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `STI9287`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TMI datasheet](docs/sti9287-datasheet.pdf) (10 pp, sha256 `3f6e57b764306e99`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
