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 | VIN | power_in | Input supply pin. Operating range 8V to 28V (absolute max 36V). Decouple with a 10uF ceramic capacitor placed close to the pin. |+| 2 | GATE | output | Gate drive output for the external boost NMOS power switch. Source current 30uA typ, sink current 60uA typ. |+| 3 | GND | power_in | Device ground reference. Tie to the system ground plane. |+| 4 | CS | input | Current sense input for the boost switch cycle-by-cycle current limit. Over-current protection threshold is 330mV typ (referenced to GND across the source-sense resistor). |+| 5 | FB | input | Regulator feedback input. Sensed against a 300mV (295.5-304.5mV) internal reference; connect an external current-sense resistor RFB from FB to GND to set LED current per ILED = 0.3V / RFB. |+| 6 | COMP | passive | Error-amplifier compensation node. Connect an external RC network (typ Rcomp=47kOhm series with Ccomp=33nF to GND) to set loop bandwidth and stability. EA transconductance 100uA/V typ. |+| 7 | OVP | input | Over-voltage protection sense input. Connect an external resistive divider from the boost output (V+) to GND; OVP trips at 2V typ (1.8-2.2V) and latches off until VIN is restarted or CTRL is toggled. |+| 8 | CTRL | input | Enable and external PWM dimming control. Logic-high threshold 2.6V (max), logic-low 1V (min). Accepts an external PWM dimming signal 100Hz-1kHz with 1%-100% duty cycle. Internal 150kOhm pull-down. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LOWPOWER |+| Package | SOP-8 |+| Category | LED-drv |+| Pins | 8 |++## Ordering variants++- `LP3350SOF`++## CAD (KiCad official)++- Symbol: `LP3350SOF`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LOWPOWER datasheet](docs/lp3350sof-datasheet.pdf) (7 pp, sha256 `6b1d938d9f48e0bd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
