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 | LX | output | Output switching node. Drain of the internal 100mΩ, 4A N-MOSFET switch. Connects to the boost inductor and Schottky diode. Absolute maximum voltage -0.3V to 33V. |+| 2 | GND | power_in | Ground pin. Should be connected to a strong ground plane for heat sinking and noise protection. |+| 3 | FB | input | Feedback reference voltage pin. Series-connect a current sense resistor between the WLED string and ground; feedback voltage is regulated to 250mV typ (240-260mV). ILED = 250mV / R1. Feedback input current typ 50nA. |+| 4 | EN | input | Chip enable (active high) and PWM dimming input. VIH=1.4V min, VIL=0.4V max. High-impedance pin - connect a 100kΩ pull-down to GND when the control signal may float. Accepts PWM dimming from 100Hz to 100kHz down to 1% duty cycle. Also triggers over-voltage-protection sensing. |+| 5 | NC | unconnected | No connect. Leave floating or tie as convenient for PCB routing. |+| 6 | VIN | power_in | Supply input voltage pin. Operating range 2.7V to 24V; absolute maximum 30V. Bypass with a 1uF (10uF recommended in typ. application) ceramic capacitor to GND to reduce input noise. UVLO 2.5V typ with 0.3V hysteresis. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LOWPOWER |+| Package | SOT-23-6 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `LP3310B6F`+- `LP3310B6FQVF`++## CAD (KiCad official)++- Symbol: `LP3310B6F`+- 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:** [LOWPOWER datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588903994479951873) (9 pp, sha256 `bc3c58dac4759412`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
