LED lighting controller
27 March 2019, Opto-Electronics

STMicroelectronics has combined its LED control know-how with advanced power technologies in a new all-in-one LED control chip designed to enable luminaires to save more energy and deliver better user experiences.

The HVLED001B controller simplifies the designing of LED lighting modules, with high energy efficiency at all dimming levels and smooth brightness control. It is the second generation of ST’s LED driver family containing high-voltage startup and sensing circuitry that simplifies connection to the AC line.

Its features support multi-platform reuse and compliance with the latest lighting regulations, and include: very accurate line and load regulation over a 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 the recognised 60 V safe limit, improving the application robustness; and frequency foldback for improved efficiency and regulation at light load, with good efficiency at medium load.
