st1s10phr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 0 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

ST1S10PHR

STMicroelectronics · DC-DC Converters · SOIC-8-EP

ST1S10PHR from STMicroelectronics, in a SOIC-8-EP. 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 VIN_A power_in Analog input supply voltage. Tie to the VIN supply source. Absolute maximum -0.3 to 20 V.
2 INH input Inhibit pin, active low. Connect to VIN_A if not used to enable the regulator. Absolute maximum -0.3 V to VIN_A.
3 VFB input Feedback voltage input for external resistor divider used to program VOUT from 0.8 V up to 0.85*VIN_SW. Absolute maximum -0.3 to 2.5 V, FB current -1 to +1 mA.
4 AGND power_in Analog ground return for the control circuitry. Connect to the ground plane, kept separate from PGND at the reference point.
5 SYNC input Synchronization and frequency select. Tie to GND for 900 kHz free-running operation, or drive with an external clock from 400 kHz to 1.2 MHz. Absolute maximum -0.3 to 6 V.
6 VIN_SW power_in Power input supply voltage for the internal switching power stage. Tie to the VIN power supply source, decoupled with a 4.7 µF capacitor. Absolute maximum -0.3 to 20 V.
7 SW output Switching node output for the external inductor of the step-down converter. Absolute maximum -0.3 to 20 V, up to 3 A output current capability.
8 PGND power_in Power ground return for the internal low-side switch. Connect to the ground plane close to the input capacitor.

Ordering variants

Same part, different packaging or reel option.

  • ST1S10PHR
  • ST1S10PHRPUR

CAD (KiCad official)

  • Symbol: ST1S10PHR
  • Footprint: Package_SO:TI_SO-PowerPAD-8
  • 3D model: SOIC-8-EP (KiCad packages3D, STEP)
  • 3D model files: st1s10phr-etched.step / st1s10phr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); st1s10phr.step / st1s10phr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
st1s10phr.step 123 KB You want the bare part, or you mark your own boards.
st1s10phr-etched.step 1.9 MB You want the part with ST1S10PHR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 486 faces against 147 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:
