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 | LPF | bidirectional | Low-pass filter pin for PWM-to-analog dimming. When HPWM dimming frequency is 10kHz-40kHz, LPF pin is left floating; when HPWM frequency is 200Hz-10kHz, a capacitor from LPF to GND is recommended to reduce output current ripple. |+| 2 | HPWM | input | HPWM signal input pin for PWM-to-analog dimming control. Input thresholds: high >=2.5V, low <=1.3V. Supports 200Hz to 40kHz dimming frequency. |+| 3 | ZVS | input | Quasi-Resonant (zero-voltage switching) detect signal input. Also used for LED open protection with a threshold Vth_ZVS typically 4V (3.8-4.2V). |+| 4 | CS | input | Current sense terminal. Senses the primary MOSFET source current across an external sense resistor. Over-current threshold Vth_ocp typ. 0.8V; leading-edge blanking ~350ns. |+| 5 | DRAIN | power_out | Drain of the integrated high-voltage MOSFET (BVdss = 100V min). Connects to the switching node of the buck converter (inductor/freewheeling diode). |+| 6 | VIN | power_in | Power supply input. Recommended operating range 9V to 30V (absolute max 35V). UVLO turn-on ~7.2V, UVLO release ~8V. |+| 7 | ADIM | input | Analog dimming input. The voltage on ADIM sets the internal reference that determines the LED current. Recommended range 0V to 5V; inner clamp ~250mV at ADIM=2.5V. |+| 8 | GND | power_in | Power ground reference for the controller and integrated MOSFET source return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | OB On Bright Elec |+| Package | SOP-8 |+| Category | LED-drv |+| Pins | 8 |++## Ordering variants++- `OB3379ZCPA-DOB3379ZCP-D`+- `OB3379ZCPA-D`+- `OB3379ZCPA-DOB3379YCP-D`+- `OB3379ZCPA-DOB3379YCPA-D`++## CAD (KiCad official)++- Symbol: `OB3379ZCPA-D`+- 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:** [OB On Bright Elec datasheet](docs/ob3379zcpa-d-datasheet.pdf) (11 pp, sha256 `3be4d3dce87cc9b3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
