Best-in-class power factor, efficiency, and reliability for LED lighting
Operating directly from the rectified mains, ST’s
HVLED001A offline controller for LED lighting
with constant-voltage primary-sensing, 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.
