SY6280AAAC

Silergy Corp · AC-DC Controllers and Regulators · SOT-23-5

SY6280AAAC from Silergy Corp, in a SOT-23-5. 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 OUT power_out Switched power output pin. Connect a 10µF decoupling capacitor to GND. Delivers up to 2A load current from the internal P-channel MOSFET (R_DS(on) ~63mΩ typ.). No body diode, so reverse current from OUT to IN is blocked when disabled.
2 GND power_in Device ground reference. Also the case position for θ_JC thermal measurement per JEDEC 51-3.
3 ISET input Current-limit programming pin. Connect a resistor R_SET from this pin to GND to set the over-current threshold: I_LIM (A) = 6800 / R_SET (Ω). Minimum programmable limit is 0.4A; operation above 2A is not recommended.
4 EN input Active-high ON/OFF enable input. V_EN(H) ≥ 2V to enable, V_EN(L) ≤ 0.8V to disable; leakage 1µA at 5V. Must not be left floating.
5 IN power_in Power input pin, 2.4V to 5.5V operating range (6V absolute maximum). Decouple with a 10µF ceramic capacitor to GND, placed close to the pin, to prevent input droop during hot-plug and to suppress ringing from output short events. UVLO threshold ~2.3V with 0.1V hysteresis.

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: SY6280AAAC
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sy6280aaac-etched.step / sy6280aaac-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sy6280aaac.step / sy6280aaac.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sy6280aaac.step 85 KB You want the bare part, or you mark your own boards.
sy6280aaac-etched.step 2.0 MB You want the part with SY6280AAAC 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 102 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:
