Product details
Overview
ICE2PCS01G from Infineon Technologies is a standalone Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends. It delivers average current control, programmable 50–250 kHz switching frequency, 3 V ±2% trimmed internal reference, 95% max duty cycle at 125 kHz, and operates across 85–265 VAC input. Used in industrial SMPS, LED drivers, and server power supplies requiring IEC 61000-3-2 Class D compliance.
For engineers reviewing the ICE2PCS01G datasheet, ICE2PCS01G pinout, ICE2PCS01G application, or ICE2PCS01G equivalent, this page provides verified technical context, validated pin functions, real-world PFC design constraints, and confirmed alternative controllers with documented functional trade-offs.
Technical Context
The ICE2PCS01G implements cascaded dual-loop control: an inner average current loop (using ISENSE and ICOMP) and an outer voltage loop (using VSENSE and VCOMP), both with external compensation networks. Its nonlinear gain block shapes current reference dynamically to maintain sinusoidal line current under varying load and input voltage.
It features cycle-by-cycle peak current limiting, soft overcurrent control acting on PWM duty via the nonlinear gain block, open-loop protection triggered when VSENSE < 0.6 V, and output overvoltage protection activated at 108% of rated VOUT. Startup is controlled by linear VCOMP ramping with 30 mA sourcing capability and window-detect level shifting below 83% VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Boost converter only; requires external MOSFET and diode; not usable in flyback or buck-derived topologies. |
| Operating Input Range | 85–265 VAC RMS; enables universal mains operation without manual range switching. |
| Switching Frequency | 50–250 kHz, set by resistor at FREQ pin; higher frequencies reduce inductor size but increase switching losses. |
| Voltage Reference | 3.0 V ±2% at 25°C; sets precise OVP threshold and VSENSE regulation point for stable 380–400 VDC bus control. |
| Gate Drive Capability | 1.5 A source / 2.0 A sink; directly drives medium-power MOSFETs (e.g., 600 V/20 A) without external buffer. |
| Protection Functions | Includes UVLO (11.0 V off / 11.8 V on), SOC, PCL, OLP (VSENSE < 0.6 V), and OVP (108% VOUT); no external fault latching required. |
| Startup Behavior | Soft-start via linear VCOMP ramp (30 mA max); limits inrush current stress on boost diode and bulk capacitor. |
Pinout & Package
ICE2PCS01G is housed in a PG-DSO-8 (SOIC-8) surface-mount package with standard 1.27 mm pitch and exposed thermal pad (non-electrical). Pin 1 is marked by notch or dot; pin numbering follows counter-clockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal reference ground | Common return path for all internal blocks; must be low-impedance connection to PCB ground plane. |
| ICOMP (Pin 2) | Current loop compensation node | Connects external RC network to stabilize inner current loop; integrates OTA2 output for average current regulation. |
| ISENSE (Pin 3) | Primary current sense input | Senses voltage drop across external shunt resistor; feeds both average current control and peak current limit circuitry. |
| FREQ (Pin 4) | Frequency programming input | Resistor-to-ground sets oscillator frequency; 50–250 kHz range enables optimization of magnetics vs. efficiency. |
| VCOMP (Pin 5) | Voltage loop compensation & soft-start node | External RC network sets outer loop stability; internal 30 mA current source enables controlled startup ramp. |
| VSENSE (Pin 6) | Output voltage feedback input | Resistive divider scales bus voltage to 3 V reference; <0.6 V triggers open-loop shutdown and standby mode. |
| VCC (Pin 7) | Positive supply input | 11–26 V DC auxiliary supply; UVLO ensures clean enable/disable; no internal clamp - external Zener recommended. |
| GATE (Pin 8) | High-current gate driver output | Drives N-channel MOSFET gate directly; 15 V clamp prevents overdrive; 1.5 A/2.0 A drive supports fast turn-on/turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Average current control architecture | Enables >0.99 PF across full load range without digital computation; eliminates need for multiplier ICs or DSP-based control. |
| External voltage and current loop compensation | Allows full customization of transient response and stability margins for diverse boost inductor values and bus capacitance. |
| Programmable switching frequency (50–250 kHz) | Permits layout- and cost-optimized selection: lower frequencies reduce EMI filter size; higher frequencies shrink magnetics. |
| Fast dynamic response during load jumps | Enhanced voltage loop reacts within 100 µs to step-load changes; maintains bus regulation within ±2% without external assist. |
| Integrated Class D compliance support | Meets IEC 61000-3-2 harmonic limits up to 2 kW without additional filtering or firmware tuning. |

| Server & Telecom Rectifiers | Medical Equipment Power Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28070 (Texas Instruments) | Dual-phase interleaved CCM controller; requires two external MOSFETs; 60–300 kHz range; no integrated soft-start current source. | Targeted at >1 kW systems needing lower EMI and reduced input/output ripple; not suitable for single-phase cost-sensitive designs. | Select UCC28070 only when interleaving is required to meet EMI class B limits or when >1.5 kW output is needed with shared thermal design. |
| L6562A (STMicroelectronics) | Single-phase CCM controller with fixed 67 kHz frequency; no programmable FREQ pin; 2.5 V reference; lower gate drive (0.8 A/1.2 A). | Optimized for fixed-frequency, low-cost consumer-grade PFC; lacks dynamic response enhancements and precise 3 V reference trimming. | Choose L6562A for cost-driven, non-critical applications where 67 kHz operation and ±5% reference tolerance are acceptable. |
Compared with UCC28070 and L6562A, ICE2PCS01G offers uniquely balanced programmability (50–250 kHz), precision (3 V ±2%), and integration (soft-start current source, nonlinear gain, dual-loop compensation), making it optimal for mid-power industrial and medical systems demanding flexibility and reliability without interleaving complexity.

FAQ
What is the minimum recommended series resistor for the ISENSE pin?
A 220 Ω resistor is recommended in series with the ISENSE pin to limit inrush current during startup, preventing damage from negative voltage spikes exceeding absolute maximum ratings. This value is specified in the datasheet's pin functionality section and validated across 85–265 VAC cold-start conditions with typical 1 mH boost inductors.
Can ICE2PCS01G operate in discontinuous conduction mode (DCM)?
The ICE2PCS01G is designed for CCM operation but transitions to DCM only under light load conditions due to inductor current decay; it does not actively regulate in DCM. The datasheet confirms that harmonic distortion remains within IEC 61000-3-2 Class D limits even in DCM, eliminating need for mode-switching logic.
Is external clamping required on the VCC pin?
Yes - the VCC pin has no internal overvoltage clamp. An external Zener diode (e.g., 24 V, 1 W) is required between VCC and GND to prevent damage from auxiliary supply transients, as stated in the Absolute Maximum Ratings table and confirmed in the Power Supply section of the datasheet.
How does the nonlinear gain block improve PFC performance?
The nonlinear gain block dynamically adjusts the current reference shape based on instantaneous line voltage, ensuring near-perfect sinusoidal input current even with distorted or unbalanced mains. This function is implemented in analog hardware and does not require microcontroller intervention or lookup tables.
