Product details
Overview
ICE3PCS03GXUMA1 from Infineon Technologies is an 8-pin Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller IC for boost-topology AC-DC front-ends. It delivers >90% system efficiency across 85–265 VAC input, supports 21–100 kHz adjustable switching frequency, integrates digital voltage-loop compensation, and provides fast dynamic response during load transients in industrial SMPS, LED drivers, and server power supplies.
For engineers reviewing the ICE3PCS03GXUMA1 datasheet, ICE3PCS03GXUMA1 pinout, ICE3PCS03GXUMA1 application, or ICE3PCS03GXUMA1 equivalent, this page details its CCM PFC control architecture, brownout protection threshold (1.25 V), gate drive clamping (15 V typ), integrated sigma-delta ADC (2.5 V ref, 3.55 kHz sampling), and external synchronization capability - all critical for high-reliability active PFC design.
Technical Context
The ICE3PCS03GXUMA1 implements a cascaded dual-loop control: an inner average current loop using analog ramp-based PWM with peak current limiting (PCL), and an outer digitally compensated voltage loop with notch-filtered sigma-delta ADC sensing (VSENSE pin, 2.5 V reference). Its nonlinear gain block decouples voltage-loop output from line-voltage variation to maintain regulation across 85–265 VAC.
Startup is managed by UVLO (12.0 V turn-on, 11.0 V turn-off) with soft-start initiated when VSENSE > 0.5 V and BOP > 1.25 V. Protection includes brownout (BOP), open-loop (OLP), first-overvoltage (OVP), and peak-current limiting - all implemented with dedicated analog comparators and logic, not software.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Boost-only CCM PFC; requires external MOSFET and diode - no DCM operation intended. |
| Input Voltage Range | 85–265 VAC line; validated for IEC 61000-3-2 Class D compliance under light-load DCM transition. |
| Switching Frequency | 21–100 kHz via external RFREQ resistor (e.g., 67 kΩ → 65 kHz); synchronized to external clock via FREQ pin. |
| Voltage Sensing | Sigma-delta ADC at VSENSE pin with 2.5 V internal reference and 3.55 kHz sampling - enables ripple-insensitive regulation. |
| Brownout Threshold | 1.25 V at BOP pin - triggers shutdown if AC-derived sense voltage falls below threshold, preventing unstable PFC operation. |
| Gate Drive Output | GATE pin drives external MOSFET with 15 V clamp (typical), supporting fast turn-on/turn-off with external RGATE resistor. |
| Current Sense Input | ISENSE accepts negative-going shunt voltage; series RCS (50 Ω typical) limits inrush current into pin during startup. |
Pinout & Package
ICE3PCS03GXUMA1 is housed in PG-DSO-8 (RoHS-compliant, surface-mount, 8-pin SOIC variant with exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ISENSE | Current sense input | Accepts negative voltage from shunt resistor; feeds both average current regulation and peak current limiter - requires 50 Ω series resistor (RCS) to limit inrush current. |
| 2 GND | IC ground reference | Common return for all internal blocks; must be low-inductance connection to power ground plane. |
| 3 ICOMP | Current loop compensation | Connects external capacitor (e.g., 4.7 nF) to integrate OTA6 output - sets current-loop pole-zero for stability across load range. |
| 4 FREQ | Frequency setting/sync input | Accepts resistor-to-ground for frequency setting (VFREQ ≈ 1 V) or external sync pulses (≥2.5 V, rising-edge triggered). |
| 5 BOP | Brownout protection input | Monitors scaled AC line voltage; IC disables if voltage <1.25 V - prevents operation during undervoltage conditions. |
| 6 VSENSE | Bulk voltage feedback | ADC input for output bus voltage; resistive divider scales bulk voltage to ≤2.5 V - enables digital PI compensation and OVP/OLP detection. |
| 7 VCC | IC supply input | UVLO-controlled supply (12.0 V on, 11.0 V off); requires external auxiliary supply - not bootstrapped from gate drive. |
| 8 GATE | MOSFET gate driver output | Drives external N-channel MOSFET; 15 V clamp limits gate voltage - requires external RGATE (e.g., 3.3 Ω) for dV/dt control. |
Key Features
| Feature | Design Value |
|---|---|
| Digital voltage-loop compensation | Integrated sigma-delta ADC + digital PI filter eliminates external op-amp and RC network - reduces BOM count and tuning effort. |
| Notch-filtered voltage sensing | Removes 100/120 Hz output ripple before regulation - ensures stable bus voltage control without oscillation or overshoot. |
| External synchronization support | FREQ pin accepts external clock pulses (rising-edge triggered, ≥2.5 V) - enables multi-phase PFC interleaving or EMI spread-spectrum alignment. |
| Enhanced dynamic response | Soft-start and nonlinear gain block enable <200 ms bulk voltage rise to 95% rated level - minimizes stress on bulk capacitor and rectifier. |
| Comprehensive protection suite | Dedicated analog comparators for BOP, OVP, OLP, and PCL - independent of digital loop timing for fail-safe shutdown. |
Applications
| Industrial Switch-Mode Power Supplies | Server & Telecom Rectifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCM PFC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28070DR | Analog dual-loop controller with external op-amps; no integrated ADC or digital compensation - requires more external components. | Lacks notch filtering and digital PI; less effective at rejecting 100/120 Hz ripple in high-precision bus regulation. | Preferred when analog tuning flexibility is required and cost-per-component is prioritized over BOM count. |
| FAN9612M | Fixed 65 kHz frequency; no external frequency adjustment or synchronization capability - lacks FREQ pin functionality. | Not suitable for EMI-sensitive or multi-phase systems requiring frequency alignment or spread-spectrum operation. | Selected for cost-sensitive, single-phase applications where fixed-frequency operation is acceptable. |
Compared with UCC28070DR and FAN9612M, ICE3PCS03GXUMA1 uniquely combines digital voltage-loop compensation, external synchronization, and notch-filtered sensing - enabling fewer external parts, tighter bus regulation, and EMI-optimized multi-phase deployment without sacrificing reliability.

FAQ
What is the recommended external resistor value for 65 kHz operation?
The datasheet specifies a 67 kΩ resistor (RFREQ) between FREQ pin and GND to achieve 65 kHz typical switching frequency. This value assumes standard operating conditions (25°C, VCC = 15 V); tolerance and temperature drift of RFREQ directly affect frequency accuracy - ±1% metal-film resistor is recommended for production designs.
Can ICE3PCS03GXUMA1 operate without an auxiliary VCC supply?
No - ICE3PCS03GXUMA1 requires an external auxiliary supply connected to VCC pin; it does not support bootstrap or self-supply from the gate driver. The IC draws 6.4 mA during operation and enters standby (1.4 mA) only when VSENSE is pulled below 0.5 V - no internal charge pump or high-voltage start-up circuit is integrated.
How does the notch filter improve voltage regulation stability?
The integrated notch filter removes 100/120 Hz ripple from the VSENSE signal before digitization, preventing ripple-induced oscillation in the digital PI compensator. This allows tight bus voltage regulation (±1%) even with high-ESR bulk capacitors, eliminating need for additional analog filtering or larger capacitance.
What protection features activate during bulk capacitor overvoltage?
First Over-Voltage Protection (OVP) triggers when VSENSE exceeds 2.7 V (corresponding to ~430 VDC bulk voltage with standard 1.5 MΩ/18.85 kΩ divider), forcing immediate gate shutdown. Unlike slower digital OVP, this is an analog comparator-based function with <500 ns response - ensuring MOSFET safety before capacitor stress limits are exceeded.
