ICE3PCS03G

Infineon · AC-DC Controllers and Regulators · SOIC-8

ICE3PCS03G from Infineon, in a SOIC-8. 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 ISENSE input Current Sense Input. Senses the voltage drop across the external shunt resistor (R_SHUNT). Input signal for average current regulation in the current loop and fed to the peak current limitation block. A ~50Ω series resistor (R_CS) is recommended to limit inrush current into the pin.
2 GND power_in IC ground reference potential.
3 ICOMP passive Current Loop Compensation. Low-pass filter and compensation node for the current control loop. External capacitor to this pin integrates the OTA6 output current and averages the current sense signal (typ. 4.7nF/25V).
4 FREQ passive Switching Frequency Setting. External resistor to GND sets the oscillator switching frequency (range 21 kHz to 250 kHz). Pin voltage is typically 1V; also usable for external synchronization via pulse injection.
5 BOP input Brownout Protection input. Monitors the AC input voltage for brownout protection. The IC begins operating when V(BOP) > 1.25V.
6 VSENSE input Bulk Voltage Sense. Connected via a resistive divider to the bulk (output) voltage; VSENSE relative to GND represents the output voltage. Monitored for voltage regulation, over-voltage protection, and open-loop protection. Pulling below 0.5V forces the IC into standby.
7 VCC power_in IC supply voltage (up to 25V absolute max). Powers the ground-related IC section. UVLO turn-on at 12.0V, turn-off at ~11V. Typical operating current ~6.4mA during normal operation.
8 GATE output Gate Drive output for the external PFC MOSFET. Gate drive voltage is clamped at 15V (typical). Maximum duty cycle 95% (typical).

Same part, different packaging or reel option.

  • ICE3PCS03G

CAD (KiCad official)

  • Symbol: ICE3PCS03G
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ice3pcs03g-etched.step / ice3pcs03g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ice3pcs03g.step / ice3pcs03g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ice3pcs03g.step 122 KB You want the bare part, or you mark your own boards.
ice3pcs03g-etched.step 2.4 MB You want the part with ICE3PCS03G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 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:
