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). |
