Product details
Overview
ICE2PCS04GXT from Infineon Technologies is an 8-pin standalone Power Factor Correction (PFC) controller IC for boost-topology converters operating in Continuous Conduction Mode (CCM) with average current control, fixed 133 kHz switching frequency, input brown-out protection (VINS threshold: 0.71 V turn-off / 1.5 V turn-on), and 3 V ±2% internal reference voltage. It delivers precise output bus regulation in universal-input AC-DC power supplies (85–265 VAC) for Class D IEC 61000-3-2 compliance.
For engineers reviewing the ICE2PCS04GXT datasheet, ICE2PCS04GXT pinout, ICE2PCS04GXT application, or ICE2PCS04GXT equivalent, this controller supports fast startup with soft-start ramping, external voltage/current loop compensation, cycle-by-cycle peak current limiting, and gate drive with 1.5 A source / 2.0 A sink capability - critical for high-reliability industrial and computing power supply designs.
Technical Context
The ICE2PCS04GXT implements a cascaded dual-loop control architecture: an inner average current loop (sensed via ISENSE, compensated at ICOMP) shapes sinusoidal input current, while an outer voltage loop (sensed at VSENSE, compensated at VCOMP) regulates output bus voltage to 3 V reference. It operates exclusively in CCM under normal load, entering DCM only at light loads - maintaining Class D harmonic compliance.
Its protection subsystem integrates five independent functions: VCC UVLO (11.0 V off / 11.8 V on), input brown-out detection (VINS < 0.71 V), output over-voltage protection (OVP), open-loop detection (OLP), and soft overcurrent control (SOC) - all triggering controlled standby mode without latch-up. The GATE driver delivers rail-to-rail swing with internal 15.0 V clamp.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 133 kHz ±5% at 25°C - fixed internal oscillator enables predictable EMI filter design and eliminates external timing components. |
| Input Voltage Range | 85–265 VAC - supports universal mains input without hardware reconfiguration. |
| VCC Operating Range | 11–26 V - compatible with standard auxiliary supplies; UVLO thresholds ensure clean start/stop sequencing. |
| Reference Voltage | 3.0 V ±2% - enables accurate 380–400 VDC output regulation via resistive divider at VSENSE. |
| GATE Drive Capability | 1.5 A source / 2.0 A sink - directly drives medium-power MOSFETs (e.g., 600 V CoolMOS™) without external buffers. |
| Brown-Out Threshold | VINS < 0.71 V (shutdown), >1.5 V (restart) - prevents unstable operation during low-line sags while avoiding nuisance tripping. |
| Max Duty Cycle | 95% typical - ensures sufficient headroom for boost converter duty ratio across full input range. |
Pinout & Package
ICE2PCS04GXT is housed in a PG-DSO-8 (SOIC-8) surface-mount package with standard 150 mil body width and 1.27 mm pitch, optimized for automated assembly and thermal performance in compact power supplies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power Ground Reference | Common return path for all internal analog/digital blocks; must be low-impedance connection to PCB ground plane. |
| 2 ICOMP | Current Loop Compensation Node | Connects external RC network to stabilize inner current control loop; integrates OTA2 output for average current regulation. |
| 3 ISENSE | Shunt Current Sense Input | Accepts voltage drop from external sense resistor (RSENSE) to enable cycle-by-cycle peak limiting and average current feedback. |
| 4 VINS | Brown-Out Detection Input | Monitors scaled rectified AC line via resistive divider; triggers shutdown below 0.71 V to prevent unstable PFC operation. |
| 5 VCOMP | Voltage Loop Compensation Node | Hosts external Type II/III compensation network to set bandwidth and phase margin of outer voltage regulation loop. |
| 6 VSENSE | Output Bus Feedback Input | Receives scaled DC bus voltage; compared internally to 3.0 V reference to generate error signal for voltage loop. |
| 7 VCC | IC Supply Input | Accepts auxiliary DC supply (11–26 V); internal UVLO ensures reliable power-on reset and brown-out recovery. |
| 8 GATE | High-Current MOSFET Driver Output | Drives external boost switch gate with 1.5 A source / 2.0 A sink; clamped to 15.0 V to protect MOSFET gate oxide. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables near-unity power factor (>0.99) and low THD across full load range without requiring complex digital computation. |
| External Loop Compensation | Independent ICOMP and VCOMP pins allow full customization of current/voltage loop dynamics for system-specific stability and transient response. |
| Fast Startup with Soft-Start | VCOMP ramps linearly during startup, limiting inrush current and preventing overshoot on DC bus during power-up. |
| Integrated Protection Suite | Five coordinated protections (UVLO, IBOP, OVP, OLP, SOC) force safe standby mode without latch-up - reducing need for external fault management logic. |
| Class D Harmonic Compliance | Guaranteed compliance with IEC 61000-3-2 Class D limits up to full rated load, even with variable line and load conditions. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS02GXT | Fixed 65 kHz switching frequency; no input brown-out detection; same pinout and compensation architecture. | Lacks brown-out protection; requires external brown-out circuitry for universal-input designs with grid instability. | Select when lower EMI priority and cost sensitivity outweigh need for integrated brown-out detection. |
| UCC28070PW | Interleaved dual-channel CCM controller; 110–265 VAC input; requires external clock sync and more external components. | Supports higher power via interleaving but increases BOM count and layout complexity; not pin-compatible. | Select for >1 kW systems where interleaving reduces input/output ripple and improves thermal distribution. |
Compared with ICE2PCS02GXT, ICE2PCS04GXT adds brown-out protection and higher 133 kHz frequency for smaller magnetics; versus UCC28070PW, it offers simpler single-channel integration at lower power, with no interleaving overhead or synchronization constraints.

FAQ
What is the purpose of the VINS pin on ICE2PCS04GXT?
The VINS pin senses a scaled version of the rectified AC input voltage via an external resistive divider. It triggers brown-out protection when voltage drops below 0.71 V (shutting down the IC) and re-enables operation above 1.5 V. This prevents unstable PFC operation during low-line conditions while avoiding nuisance shutdowns during brief sags - critical for grid-connected equipment in regions with volatile mains.
Can ICE2PCS04GXT operate without an external auxiliary supply?
No - ICE2PCS04GXT requires an external auxiliary supply connected to the VCC pin (11–26 V). It has no internal high-voltage startup circuitry. The IC draws ~300 mA during startup and ~10 mA in normal operation. An auxiliary winding on the main boost inductor or separate offline regulator is mandatory to power VCC before the PFC output reaches regulation.
How does the ICE2PCS04GXT achieve Class D compliance per IEC 61000-3-2?
ICE2PCS04GXT achieves Class D compliance through average current-mode CCM control, which inherently shapes input current to follow the sinusoidal input voltage waveform. Its fixed 133 kHz frequency, precise 3 V reference, and coordinated protection features maintain stable operation across 85–265 VAC and 0–100% load - ensuring total harmonic distortion remains below Class D limits without requiring additional filtering or firmware tuning.
Is the ICE2PCS04GXT pin-compatible with other ICE2PCS variants?
Yes - ICE2PCS04GXT shares identical PG-DSO-8 pinout and functional pin assignments with ICE2PCS01GXT, ICE2PCS02GXT, and ICE2PCS03GXT. However, internal features differ: only ICE2PCS04GXT and ICE2PCS04 include brown-out detection and 133 kHz frequency; others offer 65 kHz or lack IBOP. Swapping requires verification of feature alignment and compensation network tuning.
