FL7760AM6X

onsemi · LED Drivers · SOT-23-6

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.
