Product details
Overview
ICE2PCS05GXUMA1 from Infineon Technologies is an 8-pin standalone CCM Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends, operating across 85–265 VAC input, with programmable switching frequency (20–250 kHz), 3 V ±2% trimmed internal reference, and 95% max duty cycle at 125 kHz. It delivers fast startup, average current control, and integrated protections including OVP, SOC, and open-loop detection for industrial SMPS and Class D-compliant lighting ballasts.
For engineers reviewing the ICE2PCS05GXUMA1 datasheet, ICE2PCS05GXUMA1 pinout, ICE2PCS05GXUMA1 application, or ICE2PCS05GXUMA1 equivalent, key selection criteria include its external voltage/current loop compensation flexibility, gate drive capability (1.5 A source / 2.0 A sink), VCC UVLO thresholds (11.8 V turn-on / 11 V shutdown), and PG-DSO-8 package compatibility with high-density PFC board layouts.
Technical Context
The ICE2PCS05GXUMA1 implements a cascaded dual-loop architecture: an inner average current loop using ISENSE feedback and ICOMP compensation, and an outer voltage loop with VSENSE sensing and VCOMP compensation. Its nonlinear gain block shapes line-current harmonics to meet IEC 61000-3-2 Class D limits under both CCM and light-load DCM operation.
Frequency is set via a resistor from FREQ to GND, enabling precise EMI tuning between 20 kHz and 250 kHz. The gate driver delivers rail-to-rail output clamped at 15 V with 1.5 A peak source and 2.0 A peak sink, directly driving MOSFET gates without external buffers in typical 300–400 W PFC stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Boost converter only; requires external MOSFET and inductor - no integrated power switch. |
| Input Voltage Range | 85–265 VAC; enables universal-line operation without manual range switching. |
| Switching Frequency | 20–250 kHz, resistor-programmable on FREQ pin - allows EMI optimization and thermal trade-off tuning. |
| Reference Voltage | 3.0 V ±2% at 25°C - ensures accurate VOUT regulation and protection thresholds (e.g., OVP at 108% of rated bus). |
| Gate Drive Strength | 1.5 A source / 2.0 A sink, 15 V clamped - supports fast turn-on/turn-off of 10–50 nC gate charge MOSFETs. |
| VCC UVLO Threshold | Turn-on at 11.8 V, shutdown at 11.0 V - prevents erratic operation during brownout or auxiliary supply instability. |
| Max Duty Cycle | 95% at 125 kHz - enables high step-up ratio designs while maintaining stable CCM operation. |
Pinout & Package
ICE2PCS05GXUMA1 is housed in a RoHS-compliant PG-DSO-8 (SOIC-8) surface-mount package with standard 1.27 mm pitch and exposed pad for thermal enhancement. Pin 1 is marked by a dot or notch; pin numbering follows counter-clockwise order from top-left when viewed from component side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Signal Ground Reference | Common return path for all analog and logic circuits; 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 cycle-by-cycle peak limiting. |
| FREQ (Pin 4) | Frequency Programming Input | Resistor-to-GND sets oscillator frequency; determines switching period and EMI profile. |
| VCOMP (Pin 5) | Voltage Loop Compensation & Soft-Start | External RC network sets outer loop stability; internal ramp during startup controls gradual current rise. |
| VSENSE (Pin 6) | Output Bus Voltage Feedback | Resistive divider scales VOUT to 3 V reference; <0.6 V forces standby mode with 300 µA quiescent current. |
| VCC (Pin 7) | IC Power Supply Input | Accepts 11–26 V auxiliary supply; internal UVLO disables operation below 11 V to prevent malfunction. |
| GATE (Pin 8) | MOSFET Gate Driver Output | Directly drives external N-channel MOSFET gate; 15 V clamp avoids overdriving gate oxide. |
Key Features
| Feature | Design Value |
|---|---|
| Average Current Control Architecture | Enables sinusoidal input current draw without dedicated multiplier IC - reduces BOM count and layout complexity. |
| External Loop Compensation | Full user control over both current (ICOMP) and voltage (VCOMP) loop dynamics - supports custom transient response tuning. |
| Soft Overcurrent Protection (SOC) | Reduces PWM duty cycle gradually instead of hard cutoff - prevents abrupt load rejection and maintains system stability during overload. |
| Enhanced Dynamic Response | Window-detect circuit accelerates VOUT ramp-up during startup - achieves >83% rated bus voltage before full regulation engages. |
| Class D Compliance Ready | Meets IEC 61000-3-2 harmonic limits up to 2 kW without additional filtering - validated across full input range and load conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2PCS02GXUMA1 | Fixed 65 kHz frequency; no FREQ pin; lower gate drive (1.0 A source / 1.5 A sink); same PG-DSO-8 package. | Limited EMI tuning flexibility; suited for cost-sensitive, fixed-frequency designs where layout simplicity outweighs frequency agility. | Select when board space is constrained and EMI filter design is finalized - avoids need for frequency-setting resistor. |
| UCC28070DR | Two-phase interleaved CCM controller; 16-pin SOIC; includes phase-control logic and current-sharing interface; higher integration. | Targets >1 kW systems requiring ripple cancellation and thermal balancing - not drop-in compatible. | Choose for high-power (>600 W), low-ripple PFC stages where interleaving improves efficiency and reduces EMI filter size. |
Compared with ICE2PCS02GXUMA1, ICE2PCS05GXUMA1 offers field-tunable frequency and stronger gate drive for faster switching; versus UCC28070DR, it provides simpler single-phase implementation with lower BOM cost but lacks multi-phase coordination.

FAQ
What is the recommended external sense resistor value for ISENSE at full load?
For a typical 300 W PFC stage with 10 A peak inductor current, a 22 mΩ shunt yields ~220 mV at peak - well within the ISENSE absolute maximum rating of ±0.75 V and optimal for noise immunity. A series 220 Ω resistor (R2) is mandatory to limit inrush current into the pin during startup, per Infineon's application guidance.
Does ICE2PCS05GXUMA1 support discontinuous conduction mode (DCM)?
No - ICE2PCS05GXUMA1 is explicitly designed for continuous conduction mode (CCM) operation. Under light loads, the system may naturally enter DCM due to choke inductance and reduced current, but the IC does not regulate or optimize for DCM; its average current control loop assumes CCM behavior for accurate line-current shaping.
How is soft-start duration controlled, and what is its typical time constant?
Soft-start is implemented via internal linear ramping of the VCOMP pin voltage during startup, controlled by OTA1 sourcing up to 30 mA into the external VCOMP compensation network. With a standard 10 nF capacitor and 100 kΩ resistor, soft-start completes in ~100 ms - adjustable via RC values to match system inrush limits and bulk capacitor charging requirements.
Can VSENSE be used to force standby mode, and what is the quiescent current in that state?
Yes - pulling VSENSE below 0.6 V disables gate drive and places ICE2PCS05GXUMA1 into standby mode, reducing supply current to 300 µA. This feature enables remote power sequencing and energy-saving sleep states in smart power supplies, with full functionality restored once VSENSE rises above 0.6 V and VCC exceeds 11.8 V.
