OB3671AMP from OB(On-Bright Elec), in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Power supply input with built-in voltage clamping; recommended operating range 7V to 14V, absolute maximum -0.3V to 20V. |
| 2 | GND | power_in | Ground. |
| 3 | CMP | bidirectional | Loop compensation terminal; absolute maximum input voltage -0.3V to 7V. |
| 4 | GT | output | Gate drive terminal for the external NMOSFET; absolute maximum voltage -0.3V to 20V. |
| 5 | CS | input | Current sensing terminal connected to the sensing resistor at the NMOSFET source, setting maximum LED current; absolute maximum input voltage -0.3V to 7V. |
| 6 | LEDN | input | NMOSFET drain / LED negative terminal, with a resistor to the drain setting maximum cathode voltage; absolute maximum input voltage -0.3V to 80V. |
