Lighting Controller Enables Efficient Dimming

STMicroelectronics’ HVLED001B all-in-one LED control chip promises to save more energy and deliver better user experiences. According to its maker, the controller simplifies designing LED-lighting modules, maximizes energy efficiency at all dimming levels, and ensures smoother brightness control.

 

The HVLED001B is the second generation of ST’s LED driver family containing high-voltage startup and sensing circuitry that simplifies connection to the AC line. Features include:

SENSORS EXPO & CONFERENCE

With 65+ Technical Sessions, 100+ Leading Speakers, 10 new and updated tracks, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.
  • Support for multi-platform reuse and compliance with the latest lighting regulations
  • 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 an optocoupler, to ensure 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
  • Smart Auto-Reload Timer (ART) ensures latch-free protection for enhanced safety

 

The HVLED001B is in production now, housed in a SSOP10 package Price starts at $0.687 each/1,000. For more details, spend some time with the HVLED001B datasheet.
