SY8707ABC

Silergy Corp · LED Drivers · SOT-23-6

SY8707ABC from Silergy Corp, 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 LX passive Inductor node; connect an inductor between the IN pin and the LX pin (rated 33V absolute maximum).
2 GND power_in Ground pin.
3 TM input Test mode pin; ground this pin in the real application.
4 EN/ADIM input On/off control and dimming input: above 0.65V turns the chip on, 0.65V to 1.2V ramps LED current from 0% to 100%, and for PWM dimming apply a 100Hz to 1kHz square wave with amplitude above 1.2V.
5 IN power_in Input supply pin (2.5V to 30V) that also serves as the positive current sense pin; decouple to GND with a 1uF ceramic capacitor.
6 SEN input Negative current sense pin (limited to VIN ± 0.7V).
