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 | BS | passive | Bootstrap pin. A 0.1uF capacitor is connected between LX and BS to form a floating supply for the high-side switch driver. Absolute max 25V. |+| 2 | GND | power_in | Device ground reference. Connect to the ground plane with a low-impedance path. |+| 3 | FB | input | Adjustable version feedback input. Connect to the center of an external resistor divider from VOUT. Regulated to the internal 0.6V reference (0.588V/0.600V/0.612V). |+| 4 | EN | input | Enable input. Drive to logic-high (>=1.5V) to enable the IC; drive to logic-low (<=0.3V) to disable and enter micro-power shutdown. Absolute max 23V. |+| 5 | IN | power_in | Power supply input pin. Operating range 3.5V-18V; absolute max 23V. Bypass with a low-ESR ceramic capacitor (typically 22uF) close to the pin. |+| 6 | LX | output | Switching node. Internal high-side (120mOhm) and low-side (80mOhm) MOSFET common node. Connect to the external inductor; also references the BS bootstrap capacitor. Absolute max 23V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TMI |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `STI3470`++## CAD (KiCad official)++- Symbol: `STI3470`+- 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/sti3470-datasheet.pdf) (13 pp, sha256 `2fb3b7dd78ed2071`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
