FL7760AM6X from onsemi, 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 | VIN | power_in | Connect to the high voltage input line and supply current to the IC. |
| 2 | GND | power_in | Ground of IC. |
| 3 | DIM | input | DIM voltage sets the LED current regulation reference, switching terminates when DIM voltage is 0 V, and a bypass capacitor to GND is recommended if dimming is not used. |
| 4 | DRV | output | Driver output that connects to the MOSFET gate. |
| 5 | VCC | power_in | Supply pin for IC operation, fed from the internal VIN bias circuit and decoupled by an external VCC capacitor. |
| 6 | SEN | input | Current sense pin used to set the output LED current regulation through the high-side sense resistor connected between VIN and SEN. |
