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 | FB | input | Voltage feedback from auxiliary winding. Connected to a resistor divider from the auxiliary winding to reflect the output voltage; also used for quasi-resonant valley detection (new PWM cycle initiated when FB falls below ~0V). Absolute max -0.3 to 7V. |+| 2 | GND | power_in | Power ground. Return for VDD supply, CS sense resistor, CMP compensation capacitor, and FB divider. |+| 3 | VDD | power_in | Power supply pin. UVLO(OFF) turn-on threshold ~22.5V (VDD rising), UVLO(ON) turn-off threshold ~8.1V (VDD falling). VDD OVP at ~32V typical. Absolute max 40V. Start-up current ~3uA typ; operating current ~850uA typ at VDD=20V. |+| 4 | GATE | output | Gate driver output for external power MOSFET. Internally clamped to 12V typ to protect MOSFET gate. Rise time 80ns, fall time 30ns with CL=1nF. Absolute max -0.3 to 40V. |+| 5 | CS | input | Current sense input. Connect an external sense resistor between the MOSFET source and GND to this pin for cycle-by-cycle current limiting. Internal 300ns leading edge blanking suppresses turn-on spikes; OCP threshold ~0.7V typ (at Ton=0us). Absolute max -0.3 to 7V. |+| 6 | CMP | output | Loop compensation pin, internally connected to the error amplifier (transconductance ~40uS) output. A capacitor between CMP and GND sets loop bandwidth (<20Hz to suppress AC line ripple). Absolute max -0.3 to 7V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | OB On Bright Elec |+| Package | SOT-23-6 |+| Category | LED-drv |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `OB3636AMP`++## CAD (KiCad official)++- Symbol: `OB3636AMP`+- 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:** [OB On Bright Elec datasheet](docs/ob3636amp-datasheet.pdf) (10 pp, sha256 `e5a0e38b2dd607ab`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
