All-in-one high-voltage LED-lighting control chip for efficient dimming, enhanced accuracy and fast start-up

The HVLED001B contains high-voltage startup and sensing circuitry that simplifies connection to the AC line. Its advanced features support multi-platform reuse and compliance with the latest lighting regulations, and include:

  • Very accurate line and load regulation over wide range to ensure constant output voltage or output current
  • Constant output voltage regulation, with no need of optocoupler, ensures voltage remains below recognized 60V safe limit, improving the application robustness
  • Frequency foldback for improved efficiency and regulation at light load with good efficiency at medium load
  • Accurate and smooth dimming
  • Power-conversion efficiency greater than 90%
  • No-load power consumption less than 100mW
  • Power factor greater than 0.9, Total Harmonic Distortion (THD) below 10%
  • Low EMI at light load and medium load
  • Built-in over-current, input over-voltage, brownout, and optocoupler failure protection
  • ST’s smart Auto-Reload Timer (ART) ensures latch-free protection for enhanced safety

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.
