The HVLED001 from STMicroelectronics, Inc. is a new ac-dc controller specifically optimized for LED-lighting applications, where energy efficiency, reliability, and cost-competitiveness are key factors. Combining ST’s 25+ years of leadership in power-conversion architectures with innovative high-voltage technology, the HVLED001 enables equipment manufacturers to design high-end, professional lighting applications for commercial areas, retail shops, offices, and outdoor spaces that claim best-in-class performance with minimum bill of materials 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 (<10%), and high power-conversion efficiency (>90%) 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.
