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 | GND | power_in | Device ground return. Connect to system ground. |+| 2 | EN | input | Chip enable, active high. Logic-high threshold >= 0.4*VDD, logic-low <= 0.8V. Can be driven with a PWM signal for LED dimming. |+| 3 | COMP | output | Error amplifier output / loop-compensation node. Connect an external R-C network to ground to set frequency compensation of the current loop. |+| 4 | FB | input | Output LED-current feedback sense input. Regulates to VFB = 250mV (typ, 240-260mV) across an external sense resistor RFB; ILED = 0.25V / RFB. |+| 5 | DRV | output | Gate-drive output for the external N-channel power MOSFET. Typical drive level 5.5V; rise/fall ~50ns into 500pF. Choose a MOSFET with low RDSON at VGS=5.5V and Vth <= 2.5V. |+| 6 | CS | input | Switch/inductor peak-current sense input for cycle-by-cycle peak current control and input over-current protection. Trip threshold VCS_TH = 250mV (typ, 240-260mV); IPK <= 0.25V / RCS. |+| 7 | TOFF | input | Fixed off-time programming pin. TOFF = 0.51 * 150k * (COFF + 7.3pF) + 61ns via external capacitor COFF (recommend 22-33pF or larger). Left open, internal off-time defaults to 620ns. |+| 8 | VDD | power_in | Chip supply pin, fed from VIN through an external dropper resistor RVDD. Internal shunt regulator clamps VDD to 5.5V (IVDD < 10mA); UVLO rising 2.6V with 0.3V hysteresis. Typical operating current 1.3mA at 200kHz, 200uA in standby. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | OCX |+| Package | SOP-8 |+| Category | LED-drv |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `OC6701B`+- 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:** [OCX datasheet](docs/oc6701b-datasheet.pdf) (8 pp, sha256 `bc5762ea6dc6d18a`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
