SY8718A1ADC

Silergy Corp · LED Drivers · TSOT-23-6

SY8718A1ADC from Silergy Corp, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FB input Output current feedback pin. The output current is set by IOUT = 0.1V / RS, where RS is the current-sense resistor between the LED cathode and GND.
2 DIM input Dimming signal input. Accepts a PWM signal with duty range 5%-100% and dimming frequency 20kHz to 500kHz. VDIM_ON max = 1.5V, VDIM_OFF min = 0.4V.
3 GND power_in Ground pin. Device reference and return path for input decoupling and internal circuitry.
4 IN power_in Input supply pin. Operating range 4V to 23V (abs max 25V). Decouple this pin to GND with a 1µF (typ 22µF in the reference application) ceramic capacitor.
5 LX power_out Switching node pin. Connect this pin to the external inductor (6.8µH in the typical application). Swing between GND and VIN at 1MHz.
6 BST power_in Bootstrap pin. Supplies the high-side gate driver (VBST-LX typ 3V). Decouple this pin to LX with a 0.1µF ceramic capacitor.

Ordering variants

Same part, different packaging or reel option.

  • SY8718A1ADC

CAD (KiCad official)

  • Symbol: SY8718A1ADC
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: TSOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: sy8718a1adc-etched.step / sy8718a1adc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sy8718a1adc.step / sy8718a1adc.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sy8718a1adc.step 97 KB You want the bare part, or you mark your own boards.
sy8718a1adc-etched.step 2.0 MB You want the part with SY8718A1ADC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 491 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
