SY8104ADC

Silergy Corp · DC-DC Converters · TSOT-23-6

SY8104ADC from Silergy Corp, in a TSOT-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 FB input Feedback pin connected to the center point of the output resistor divider to program Vout = 0.6*(1+R1/R2).
2 EN input Enable control pin that must be pulled high to turn the device on and must not float; the datasheet gives EN falling threshold 0.4V and rising threshold 1.5V.
3 GND power_in Ground pin, to be connected to a maximized PCB copper area for best thermal and noise performance.
4 IN power_in Input supply pin, to be decoupled to the GND pin with at least 1uF ceramic capacitor, with the input range 4.5V to 18V.
5 LX output Inductor pin connected to the switching node of the inductor, with dynamic LX voltage limited to IN+3V to GND-5V for 10ns.
6 BS passive Bootstrap pin supplying the high-side gate driver, to be decoupled to the LX pin with a 0.1uF ceramic capacitor.

CAD (KiCad official)

  • Symbol: SY8104ADC
  • Footprint: Package_TO_SOT_SMD:TSOT-23-6
  • 3D model: TSOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: sy8104adc-etched.step / sy8104adc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sy8104adc.step / sy8104adc.glb are the bare package body.
