By combining a state-of-the-art low-voltage technology for the controller and an extremely robust 800 V technology for the power MOSFET in the same package, HVLED ICs feature an efficient, compact and cost-effective solution to drive LEDs directly from the rectified mains. The primary-side regulation cuts bill-of-material costs, while also simplifying design and reducing the space occupied by LED control circuitry.

ST’s HVLED drivers are the perfect solution to fit into very space-limited applications, such as lamp LED retrofits and compact AC-DC LED driver applications.


eDesignSuite is a comprehensive set of easy-to-use design-aid utilities ready to help you streamline the system development process with a wide range of ST products.
