STMicroelectronics STLUX385A Digital LED Lighting Driver

STMicroelectronics STLUX385A
STLUX™ Digital LED Lighting Driver

STMicroelectronics STLUX385A STLUX™ Digital LED Lighting Driver is tailored for lighting and power conversion. The STLUX385A integrates DALI (digital addressable lighting interface) for remote control and monitoring and has been successfully integrated in a wide range of architectures and applications.

The STLUX digital controllers are the world's first programmable controllers specifically optimized for lighting applications. The innovative SMED (state machine, event-driven) digital technology and the integrated microcontroller make STLUX easily programmable and versatile. It can be configured with application-specific algorithms to optimize the overall system efficiency, enabling high-performance and cost-effective lighting design.

More About SMED
SMED is a hardware state machine triggered by internal or external events. In power-supply applications, for example, a SMED can close the regulation loop and automatically switch off the circuit when it detects an overcurrent or a short circuit, so protecting the circuit. Since SMEDs are embedded, they guarantee an event reaction time shorter than that provided by standard interrupt-driven microprocessors.
