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 | Switching output; drain of the internal high-side power MOSFET (RDS(on) ~450 mΩ). Connect to the LED / inductor node of the buck converter. Rated up to 1.2 A peak (IMAX). |+| 2 | VSS | power_in | Chip ground reference. Connect to system ground. |+| 3 | DIM | input | Brightness / dimming control input. Accepts a PWM signal (up to 20 kHz) or a DC analog level (0.5 V to 2.5 V) to set LED current. Pulling DIM below 0.3 V places the device in shutdown/standby. Internally pulled up (~500 kΩ) to an internal 5 V rail; max pin voltage 6 V. |+| 4 | CS | input | High-side current-sense input. Connects to the low side of the external sense resistor RCS between VIN and CS; the internal comparator regulates LED current so that VIN − VCS ≈ 100 mV (±3%). Input bias current ~10 µA. |+| 5 | VIN | power_in | Supply input, 5.5 V to 30 V (absolute max 35 V). Powers the internal 5 V regulator, control logic, and high-side MOSFET. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MSKSEMI |+| Package | SOT89-5 |+| Category | LED-drv |+| Pins | 5 |++## Ordering variants++- `PT4115-MSMS`++## CAD (KiCad official)++- Symbol: `PT4115-MS`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT89-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MSKSEMI datasheet](docs/pt4115-ms-datasheet.pdf) (12 pp, sha256 `bb150976b1f46900`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
