Product details
Overview
ICE3PCS02GXUMA1 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, features integrated digital voltage-loop compensation, supports 21–100 kHz adjustable switching frequency, and provides dual over-voltage protection (OVP1/OVP2) for industrial SMPS and LED drivers.
For engineers reviewing the ICE3PCS02GXUMA1 datasheet, ICE3PCS02GXUMA1 pinout, ICE3PCS02GXUMA1 application, or ICE3PCS02GXUMA1 equivalent, key selection considerations include its CCM average-current control architecture, external synchronization capability at the FREQ pin, 95% max duty cycle, integrated notch-filtered sigma-delta ADC on VSENSE, and standalone operation without auxiliary controller dependency.
Technical Context
The ICE3PCS02GXUMA1 implements a cascaded dual-loop control: an inner analog current loop with external RC compensation at ICOMP and peak current limiting at ISENSE, and an outer digital voltage loop using a 3.55 kHz sigma-delta ADC on VSENSE with built-in PI compensation and notch filtering to reject 100/120 Hz bulk ripple. Its oscillator accepts either resistor-set frequency (RFREQ) or external TTL-compatible sync pulses at FREQ.
Startup sequencing is governed by UVLO on VCC (12.0 V turn-on, 11.0 V turn-off) and VSENSE monitoring (operation disabled if VSENSE < 0.5 V), enabling controlled soft-start and standby mode. Protection includes open-loop detection, second-stage OVP via dedicated OVP pin, and gate drive clamped to 15 V typical at GATE.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology Support | Boost PFC only; requires external MOSFET and inductor - no flyback or buck-boost capability. |
| Switching Frequency Range | 21–100 kHz via RFREQ resistor; enables EMI optimization and thermal trade-off tuning. |
| VSENSE Input | Sigma-delta ADC with 2.5 V internal reference and 3.55 kHz sampling - enables precise, ripple-immune bulk voltage regulation. |
| Current Sense Interface | Direct ISENSE pin with integrated peak current limit and average current loop input - eliminates need for separate current-sense amplifier. |
| Protection Features | Dual OVP (OVP1 via VSENSE, OVP2 via dedicated OVP pin), open-loop protection, and UVLO on VCC - ensures fail-safe shutdown under fault conditions. |
| Gate Drive Output | GATE pin drives external N-channel MOSFET with 15 V clamp - compatible with standard 600 V superjunction devices without external level-shifting. |
| Duty Cycle Limit | 95% maximum - prevents saturation in high-line, low-load conditions while maintaining CCM stability. |
Pinout & Package
ICE3PCS02GXUMA1 is housed in PG-DSO-8 (8-pin plastic small outline package, exposed pad, RoHS-compliant), optimized for thermal dissipation in high-power-density PFC stages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ISENSE | Current sense input | Accepts negative-going voltage from shunt resistor; feeds both average current regulation and peak current limit comparator. |
| 2 GND | IC ground reference | Common return for all analog and digital blocks; must be low-inductance connection to power ground plane. |
| 3 ICOMP | Current loop compensation node | External capacitor sets dominant pole for current loop stability; integrates OTA6 output to generate averaged current command. |
| 4 FREQ | Frequency setting/synchronization input | Resistor-to-ground sets switching frequency; external TTL pulse synchronizes falling edge of gate drive to rising edge of sync signal. |
| 5 OVP | Secondary over-voltage protection input | Dedicated pin for resistive divider from bulk bus - triggers immediate shutdown independent of VSENSE path for redundancy. |
| 6 VSENSE | Bulk voltage feedback input | Connects to resistive divider from DC bus; digitized by sigma-delta ADC for digital voltage loop control and OVP1 detection. |
| 7 VCC | IC supply input | 12–25 V operating range; UVLO threshold at 12.0 V (on) / 11.0 V (off); powers all internal circuitry including gate driver. |
| 8 GATE | MOSFET gate driver output | Push-pull output driving external N-MOSFET gate; 15 V clamp prevents gate oxide overstress; rated for 1 A peak sink/source. |
Key Features
| Feature | Design Value |
|---|---|
| Digital voltage loop compensation | Integrated PI algorithm with notch filter eliminates external op-amps and compensating networks - reduces BOM count and layout sensitivity. |
| External current loop compensation | ICOMP pin allows user-tuned phase margin and bandwidth via single capacitor - enables robust stability across wide choke inductance ranges. |
| Fast dynamic response during load jump | Soft-start and digital loop enable <200 ms bulk voltage rise to 95% of setpoint - minimizes stress on bulk capacitor and downstream converters. |
| Enhanced dynamic response without input current distortion | Nonlinear gain block decouples voltage loop output from line voltage variation - maintains sinusoidal input current shape from 85–265 VAC. |
| Lowest external component count | Only 7 passive components required for full-function PFC (RSHUNT, RFREQ, RCS, CICOMP, RBVS1–6) - simplifies design validation and production test. |
Applications
| Industrial AC-DC Power Supplies | LED Driver Front-Ends |
|---|---|
|

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-amp compensation; no integrated ADC or notch filter; requires more external components. | Lacks digital voltage loop - less immune to bulk ripple; slower transient response; higher design effort for stability tuning. | Preferred where analog design heritage exists and cost-per-component is prioritized over design cycle time. |
| FAN9612MJX | Fixed-frequency CCM controller (65 kHz); no frequency adjustment or external sync; analog voltage loop with external compensation. | No programmable frequency or sync capability; limited flexibility for EMI compliance across multiple product variants. | Selected for high-volume, fixed-spec designs where BOM simplicity outweighs feature flexibility. |
Compared with UCC28070DR and FAN9612MJX, ICE3PCS02GXUMA1 offers superior dynamic response due to its digital voltage loop and notch filtering, lower external part count, and greater system-level safety via dual OVP - making it optimal for next-generation industrial and lighting platforms demanding rapid design turnaround and high reliability.

FAQ
What is the minimum recommended value for the RFREQ resistor?
The RFREQ resistor sets switching frequency between 21 kHz and 100 kHz. A 67 kΩ resistor yields ~65 kHz per datasheet Figure 4. Minimum RFREQ is 15 kΩ (corresponding to ~100 kHz). Values below 15 kΩ risk exceeding internal oscillator limits and reducing gate drive strength stability.
Can ICE3PCS02GXUMA1 operate without an external auxiliary supply?
No - the IC requires a regulated 12–25 V supply on VCC, typically derived from an auxiliary winding on the boost inductor or a dedicated offline regulator. The IC lacks integrated high-voltage start-up circuitry and relies on external bias for initial operation and UVLO monitoring.
How does the dual OVP architecture improve system safety?
OVP1 uses the VSENSE ADC path for precise, digitally filtered overvoltage detection. OVP2 uses the dedicated OVP pin for independent, analog-fast shutdown (<500 ns response). This redundancy ensures protection remains active even if one path fails - meeting IEC 62368-1 reinforced insulation requirements.
Is external current loop compensation mandatory?
Yes - the ICOMP pin requires an external capacitor (e.g., 4.7 nF) to integrate the current error signal and stabilize the inner current loop. Omitting this capacitor causes instability, current overshoot, and potential MOSFET failure due to uncontrolled duty cycle modulation.
