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.

STEVAL-ILL075V1 STLUX385A Evaluation Board

The STEVAL-ILL075V1 evaluation board is designed to help familiarize the user with the STLUX family of digital controllers and their innovative SMED (state machine, event driven) architecture. A convenient GUI enables the user to quickly generate the optimal SMED configuration for the application. The external pins make it easy to inject SMED events and capture the SMED controlled PWM clock, thereby helping the user to validate the SMED configuration. Alternatively, the application circuit can be driven directly from the evaluation board.

Features
  • All STLUX385A pins available on connectors
  • Convenient tool for validating SMED algorithms
  • Graphical interface for SMED configuration
  • On-board components for tutorial
  • Micro-USB port for PC connectivity
  • USB, external or SWIM power supply
  • SWIM interface with STLINK or RLINK connectors
  • Four extra footprint areas for SOT23-6 and one for SO8
  • One external clock (HSE) footprint area
  • RoHS compliant
