SD8910G

SHOUDING · DC-DC Converters · SOT-23-6

SD8910G from SHOUDING, in a SOT-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 BST passive High-side gate drive bootstrap pin. A 0.1uF~1uF capacitor must be connected from BST to LX to boost the gate drive and fully turn on the internal high-side NMOS.
2 GND power_in Device ground return pin.
3 FB input Voltage feedback input. Connect a resistive divider from VOUT to FB to GND; the loop regulates FB to the internal 0.6V reference.
4 SHDN input Enable input. Pull high to turn the IC on, pull low to turn it off. Can be tied to VIN through a 100kΩ resistor for self-startup.
5 VIN power_in Power supply input, 4.5V to 21V. Place the input capacitor(s) as close as possible from VIN to GND to minimize noise and switching ringing.
6 LX output Power switching node between the internal high-side and low-side MOSFETs. Connect the external inductor from LX to VOUT; also the bottom terminal of the BST bootstrap capacitor.

Ordering variants

Same part, different packaging or reel option.

  • SD8910GS6CTR

CAD (KiCad official)

  • Symbol: SD8910G
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: sd8910g-etched.step / sd8910g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd8910g.step / sd8910g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sd8910g.step 97 KB You want the bare part, or you mark your own boards.
sd8910g-etched.step 1.8 MB You want the part with SD8910G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 436 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:

  • Datasheet: SHOUDING datasheet (9 pp, sha256 b07def98d87038c2, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
