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 | BOFO | output | Boost Follower setting. An external DC voltage on this pin indicates the PWM output power level; used to select the boost follower low step. Set with an external resistor divider (R_BOFO1..2, ~200 kΩ). |+| 2 | ISENSE | input | Current Sense Input. Senses the voltage drop across the external shunt resistor R_SHUNT for average current control loop and peak current limitation. A series resistor R_CS (~50 Ω) is recommended in series to limit inrush current into the pin. |+| 3 | SGND | power_in | Signal Ground. Ground reference of the IC signal-level circuitry; kept separate from the power/gate switching ground (PGND). |+| 4 | ICOMP | output | Current Loop Compensation. Low-pass filter/compensation node for the current control loop; external capacitor C_ICOMP (~4.7 nF/25 V) to SGND integrates the OTA6 output and averages the current sense signal. Internally shorted to 5 V in standby. |+| 5 | FREQ | input | Switching Frequency Setting. Set the operating frequency (21 kHz to 100 kHz) via a resistor R_FREQ to SGND (e.g. 67 kΩ → ~65 kHz). Also serves as the external synchronization input when driven by an external pulse >2.5 V. |+| 6 | VB_OK | output | Bulk Voltage OK signal. Internally pulled up to 5 V once the bulk voltage exceeds 95% of the rated level; pulled to ground when VSENSE falls below the VBTHL_EN threshold. Can be used to enable the downstream PWM IC or an inrush relay. |+| 7 | VBTHL_EN | input | PFC Enable Function / VB_OK turn-off threshold. An external reference sets the VB_OK signal turn-off threshold. Pulling this pin below 0.5 V shuts down the IC. |+| 8 | VREF | power_out | Voltage Reference. 5 V internal regulator output with minimum 5 mA sourcing capability; bypass with ~100 nF/25 V to SGND. |+| 9 | BOP | input | Brownout Protection. Monitors the AC input voltage for brownout protection and line-range selection via an external RC divider from the rectified AC (BOP threshold >1.25 V for start-up). |+| 10 | OVP | input | Over Voltage Protection. Additional resistive divider from bulk voltage to SGND sets the secondary over-voltage protection threshold to ensure safe system operation. |+| 11 | VSENSE | input | Bulk Voltage Sense. Connected via a resistive divider to the boost output bulk voltage; feeds the sigma-delta ADC (2.5 V internal reference, 3.55 kHz sampling) used for voltage regulation, over-voltage and open-loop protection. |+| 12 | VCC | power_in | IC Supply Voltage. Main supply for the IC section, up to 25 V. UVLO turn-on at 12.0 V (with VSENSE >0.5 V and BOP >1.25 V); turn-off below 11 V. Typical operating current 6.7 mA, standby ~1.4 mA. |+| 13 | GATE | output | Gate Drive Output for the external PFC boost MOSFET. Gate drive voltage is clamped at 15 V (typical); series resistor R_GATE ~3.3 Ω recommended. |+| 14 | PGND | power_in | Power Ground / Gate Switching Ground. Return path for the gate driver current; kept separate from SGND for noise isolation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon |+| Package | SOIC-14 |+| Category | PMIC |+| Pins | 14 |++## Ordering variants++- `ICE3PCS01GG`++## CAD (KiCad official)++- Symbol: `ICE3PCS01G`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon datasheet](docs/ice3pcs01g-datasheet.pdf) (22 pp, sha256 `24cecdf8968137bc`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
