STMicroelectronics Reveals State-Of-The-Art Lighting Controller for Even Greater Energy Savings with Convenience and Simplicity

All-in-one high-voltage LED-lighting control chip meets latest demands for efficient dimming
Enhanced accuracy and fast start-up ensure superior user experience
Lighting innovator TCI uses STs new LED driver to increase energy savings, safety, and usability


18 February 2019, STMicroelectronics (NYSE:STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has combined its cutting-edge LED-control know-how with advanced power technologies in a new all-in-one LED control chip that enables future luminaires to save more energy and deliver better user experiences.
The HVLED001B controller simplifies designing LED-lighting modules, maximizes energy efficiency at all dimming levels, and ensures smoother brightness control. Lighting innovator TCI of Italy, a lead customer, has already designed forthcoming products containing the new chip to increase energy savings, safety, and usability.
Explaining that to create mid- and high-power LED luminaires to satisfy the latest lighting regulations and market demands is no easy challenge, a technical spokesperson for TCI said, STs new LED driver enabled us to achieve our high performance targets, leveraging built-in features that simplify design and reduce the bill of materials. LED power-up is extremely fast, taking less than 0.4 seconds, and efficiency remains very high even at the lower dimming levels where conventional drivers can lose their edge.
Matteo Lo Presti, Executive Vice President, Analog Sub-Group General Manager in STs Analog, MEMS and Sensors Group, added, As well as further improving energy efficiency under all operating conditions, the latest luminaires must support smart-grid management and power quality by increasing power factor and reducing harmonic distortion. The HVLED001B makes these targets achievable, at the same time as supporting improved start-up performance and dimming accuracy.
The HVLED001B is in production now, housed in the familiar and compact SSOP10 package, and available from $0.687 for orders of 1000 pieces.
Further technical information:
The HVLED001B is the second generation of STs LED driver family containing 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 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
STs smart Auto-Reload Timer (ART) ensures latch-free protection for enhanced safety
