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 | FB | input | Output voltage feedback input. Connect FB to the center point of the external resistor divider. Regulated feedback voltage is 0.6V (±1.5%). FB input leakage is ±0.5µA max. |+| 2 | EN | input | Enable input. Drive high (>1.05V typ, 1.20V max) to enable the IC; drive low (<0.90V) to disable and enter micro-power shutdown mode. Do not float EN. Max input rating 20V; 120mV hysteresis; 300µs enable delay. |+| 3 | GND | power_in | Ground pin. Return for the low-side MOSFET and all internal circuitry. Connect to a large copper area for thermal performance. |+| 4 | IN | power_in | Power supply input pin. Accepts 4.5V to 18V (20V absolute max). Bypass with a ceramic capacitor placed close to the pin. OVP threshold ~19V typ. |+| 5 | LX | power_out | Switching node. Connect to the external inductor. Internal high-side and low-side MOSFETs switch this node between IN and GND. Absolute max -0.3V to 20V (-4.5V to 22V for <10ns transients). |+| 6 | BS | passive | Bootstrap pin. A capacitor (typ 0.1µF) connected between BS and LX forms a floating supply for the high-side MOSFET gate driver. Absolute max 23V referenced to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TMI |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TMI3255SF`++## CAD (KiCad official)++- Symbol: `TMI3255SF`+- 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/tmi3255sf-datasheet.pdf) (14 pp, sha256 `6f4c0c6a566eb888`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
