STMicroelectronics has announced an AC-DC controller geared for LED-lighting applications that necessitate industry-leading energy efficiency, reliability and cost-competitiveness. According to the company, the HVLED001 allows equipment manufacturers to design high-end, professional lighting applications for commercial areas, retail shops, offices and outdoor spaces that claim to deliver best-in-class performance with minimum BOM and assembly costs.

Operating directly from the rectified mains, the HVLED001 uniquely integrates both high- and low-voltage circuitry on the same chip, eliminating the cost of external high-voltage circuitry. The high power factor (>0.9), low total harmonic distortion (THD) (<10 per cent) and high power-conversion efficiency (>90 per cent) ensure compliance with the most stringent lighting standards in an efficient, compact and cost-effective solution to drive LEDs in the power range from 20W up to 150W.

The HVLED001 features an embedded 800V high-voltage start-up, ensuring LED start-up in less than 0.5s, along with reduced BOM and increased robustness; constant output-voltage primary-side control with ±2 per cent accuracy ensuring a stable light experience across multiple LED-light sources; and embedded multiplier and THD optimiser that provides fast response to line-voltage variations.

In addition, the AC-DC controller has an adjustable frequency foldback for improved efficiency and regulation under low load-dimming conditions; and a comprehensive smart protections including input overvoltage, overcurrent, brownout and opto-coupler failure, all latch-free thanks to a smart auto-restart timer.

Housed in a compact SO10 package, the HVLED001 is available in volume with a price of $0.5 in quantities of 1k units.
