STLUXTM turns on your innovative ideas

STLUXTM 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 STLUXTM 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.

The first member of the family, STLUX385A, also integrates DALI (digital addressable lighting interface) for remote control and monitoring.

Features and benefits

  • 6 SMED-controlled PWMs providing full control of any power conversion stage
  • Integrated DALI enabling control, communication and monitoring functions
  • Integrated digital core making STLUX easy to use and programmable
  • New customizable and load-tailored algorithms ensuring very high efficiency
  • Fault detector improving reliability
  • Single-chip solution saving space when compared to discrete solutions

What is SMED?

SMED is a hardware state machine triggered by internal or external events. It is designed to replace and extend the functionalities of traditional analog architecture. 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.
