Introduction – Addressing Core Industry Pain Points
Power supply designers face three persistent challenges with power factor correction (PFC): efficiency loss from hard switching (traditional PFC controllers waste 2-5% of input power), electromagnetic interference (EMI) compliance (high-frequency switching generates noise requiring costly filtering), and complexity of balancing CCM (high efficiency at high power) vs. DCM (simpler but lower efficiency). CrM PFC Control ICs – integrated circuits specifically designed for power factor correction circuits operating in Critical Conduction Mode (CrM) – solve these problems through innovative zero-current switching. By precisely detecting the zero-crossing point of the switching transistor current, these ICs enable lossless switching, effectively reducing switching losses and improving overall system efficiency. CrM mode lies between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM), balancing efficiency with electromagnetic interference (EMI) control advantages. Widely used in high-efficiency switching power supplies, industrial power supplies, LED drivers, EV chargers, and household appliances, CrM PFC ICs meet stringent international energy efficiency and EMI standards. They typically integrate over-voltage, under-voltage, soft-start, over-temperature protections, and frequency modulation, supporting diverse topologies to achieve an optimal balance of high efficiency, low cost, and reliability. For power supply OEMs, semiconductor procurement managers, and application engineers, the critical decisions now center on power rating (<300W vs. >300W), application (Consumer Electronics, Industrial), and the protection features/package type that balance efficiency against cost.

New Industry Depth (6-Month Data – Late 2025 to Early 2026)
- Energy efficiency regulation tightening – In December 2025, the US Department of Energy (DOE) updated Level VI efficiency standards for external power supplies, requiring >0.9 power factor for >100W units. This accelerated CrM PFC IC adoption in laptop adapters and LED drivers.
- GaN integration trend – In January 2026, Texas Instruments launched a CrM PFC controller with integrated GaN driver, reducing external component count by 40% and achieving 99% efficiency in 300W designs.
- Discrete vs. process manufacturing realities – Unlike process manufacturing (e.g., continuous chemical production), CrM PFC control IC production involves discrete wafer fabrication, testing, and packaging – each IC is individually tested for zero-crossing detection accuracy, protection thresholds, and frequency modulation. This creates unique challenges:
- Wafer fabrication – Analog CMOS or BiCMOS process. Threshold voltage (Vth) variation affects zero-crossing detection accuracy. Each wafer lot tested.
- Zero-crossing detection accuracy – IC must detect inductor current zero-crossing within ±50ns for lossless switching. Trimmed during wafer test.
- Protection threshold accuracy – Over-voltage (OVP), under-voltage (UVLO), over-temperature (OTP) thresholds ±5% tolerance. Laser-trimmed per die.
- Frequency dithering – Spread-spectrum frequency modulation reduces EMI. Modulation depth and rate tested per batch.
- Temperature range – Commercial (0-70°C) vs. industrial (-40-85°C) grade testing. Industrial grade requires extended temperature characterization.
Typical User Case – 150W LED Driver (Commercial Lighting, 2026)
A commercial lighting OEM (100,000 units/year) redesigned a 150W LED driver using a CrM PFC controller (Onsemi NCP1608, <300W rating) replacing a CCM controller. Results:
- Power factor: 0.97 (CrM) vs. 0.95 (CCM) – improved grid compatibility
- Efficiency: 94% (CrM) vs. 92% (CCM) – 2 percentage point gain, reducing heat sink size
- EMI filter components: 25% fewer components (CrM’s frequency dithering reduces peak EMI)
- IC cost: $1.15 (CrM) vs. $0.95 (CCM) – 21% higher, but system BOM savings offset
The technical challenge overcome: maintaining CrM operation at light load (frequency becomes very high, increasing switching losses). The solution used a controller with valley skipping and frequency foldback (Onsemi’s “frequency clamp”). This case demonstrates that <300W CrM PFC ICs deliver efficiency and EMI benefits for LED drivers.
Exclusive Insight – The “CrM vs. CCM vs. DCM Positioning”
Industry analysis often treats CrM as a niche mode. However, power level and application analysis (Q1 2026, n=20 power supply design engineers) reveals optimal PFC mode selection:
| PFC Mode | Power Range | Efficiency | EMI | Complexity | Best Application |
|---|---|---|---|---|---|
| DCM (Discontinuous) | <150W | Moderate | Good (low) | Low | Low-cost chargers, <75W |
| CrM (Critical) | 100-500W | High | Moderate | Medium | LED drivers, laptop adapters, appliances |
| CCM (Continuous) | >300W | Very High | Poor (high) | High | Server PSUs, EV chargers, industrial |
The key insight: CrM occupies the “sweet spot” (100-500W) – higher efficiency than DCM, simpler than CCM, with manageable EMI. CrM is optimal for LED drivers (150W), gaming console PSUs (300W), and appliance power supplies (200-400W). <300W CrM ICs dominate unit volume (60%); >300W CrM ICs are less common (CCM preferred above 500W).
Policy and Technology Outlook (2026-2032)
- EU Ecodesign Regulation (EU) 2019/1782 – External power supplies >100W require power factor >0.9. CrM PFC ICs are compliant.
- 80 PLUS certification – Computer PSU certification (Bronze, Silver, Gold, Platinum, Titanium) requires PFC and high efficiency. CrM PFC used in Gold/Platinum units (300-500W).
- China Energy Label (CEL) – Level 3-5 efficiency for power supplies mandates PFC >0.9 for >150W. Domestic IC suppliers (Chipown, Hynetek, JoulWatt) gaining share.
- Next frontier: bridgeless totem-pole CrM PFC – Research prototypes (2026) use GaN switches in bridgeless totem-pole topology with CrM control, achieving 98.5% efficiency at 300W. Commercial availability 2028-2029.
Conclusion
The CrM PFC Control ICs market is growing at 8.2% CAGR, driven by energy efficiency regulations (DOE Level VI, EU Ecodesign), LED lighting adoption, and power supply efficiency requirements. <300W CrM ICs dominate unit volume (60%) for consumer electronics (LED drivers, laptop adapters). >300W CrM ICs serve higher-power industrial and EV charger applications (40% share). Consumer electronics is the largest application (55%). The discrete semiconductor manufacturing nature of CrM PFC ICs – wafer fabrication, zero-crossing detection trimming, protection threshold laser-trimming – favors established analog IC leaders (Texas Instruments, Onsemi, STMicroelectronics, Power Integrations, Renesas, Microchip) and emerging Chinese suppliers (Chipown, Hynetek, JoulWatt). For 2026-2032, the winning strategy is offering both <300W and >300W product lines, integrating GaN drivers for high-efficiency designs, and expanding industrial temperature range (-40 to 85°C) for industrial and EV applications.
