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). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `ICE3PCS03G`++## CAD (KiCad official)++- Symbol: `ICE3PCS03G`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon datasheet](docs/ice3pcs03g-datasheet.pdf) (20 pp, sha256 `0c103622b0ab1aca`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
