Infineon ICL5102HV Integrated two-stage PFC + LLC/LCC controller

ICL5102HV control IC for LED drivers offers a unique one-package solution for lighting applications up to 350 W, supporting LLC/LCC topology. It is particularly designed to deliver the best performance of total harmonic distortions (THD) and power factor (PF). Compared to level-shifter technology, the integrated coreless transformer not only further reduces the loss at high operation frequency, but also enhances the capability of handling huge negative voltage (-600 V on HSGND).

Key features

• Coreless Transformer HS Drive
• 80 VAC Capable
• Resonant Half-bridge (HB) Controller with Fixed or Variable Switching Frequency Control
• Maximum 500 kHz HB Switching Frequency and Soft-start Frequency up to 1.3 MHz

Additional features:

• Resonant HB burst mode (BM) ensures power limitation and low standby power <300 mW
• Excellent system efficiency up to 94%
• Integrated High-side MOSFET driver with coreless transformer
• PFC controller with Critical Conduction Mode (CrCM) + Discontinuous Conduction Mode (DCM)
• Low number of external components required, allowing an optimized BOM and form factor
• Comprehensive set of protection features with auto-restart reaction:
  • Input brown-out protection
