STMicroelectronics – HVLED Lighting the future
A complete portfolio of top-performance mains voltage LED drivers, providing high efficiency and reliability in a compact form factor
The design of new generation mid- and high-power LED lighting is a relentless struggle for energy efficiency, reliability and cost competitiveness with no compromise in light quality. The HVLED family embodies ST’s expertise in power conversion and high-voltage silicon technologies, packing into a small form factor all the functions required for highperformance LED drivers. Meeting the most stringent regulations for power efficiency and quality, ST’s HVLED ICs
create an enhanced lighting experience.
Key features & benefits
• On-chip 800 V high-voltage start-up for fast LED turn-on time (less than 0.5 s)
• All constant-voltage / constant-current primary-side regulation topologies
supported for maximum design flexibility
• Quasi-resonant topology with frequency fold-back for high efficiency with low loads (dimming) (HVLED001)
• Primary-side control loop does not require an opto-coupler; enables very small form factors and simplified designs
• Multiplier-based structure for excellent power factor (PF) and total harmonic
distortion (THD) over wide variations in line voltage (HVLED001)
• High power factor (up to 0.9) over a wide input voltage range for maximum
efficiency
• Full set of advanced protection features ensures the highest reliability
IDEAL FOR
LED applications up to 80 W in a single-stage configuration and 150 W in a two-stage configuration such as:
• Bulbs and spotlights for incandescent lamp replacement
• Professional lighting
• High-bay lighting fixtures
• Street-lighting solutions
