Product Overview

STEVAL-ILL031V1 is a digital constant current controller for LED driving based on STM8S208RB. This demonstration board present a new digital approach to performing real average current control on an LED streetlighting platform. This LED streetlight platform is developed on a DC/DC inverse buck converter, taking advantage of power switch control and conditioning signal circuitry for current sensing. The hardware is mainly composed of the power conversion section and the control stage, based on the microcontroller unit. From a common DC voltage input the 4 strings are driven by 4 inverse DC/DC buck converters. The control stage is based on an STM8S208RB. Benefits of this design include low energy consumption, low maintenance, and reduced size and weight. The solution is customised for streetlighting applications, but can be extended to many other segments.
  • DC input voltage of 48V
  • Buck stage adapts output voltage to drive LEDs with selected current
  • Four DC/DC buck converters allow driving of 4 LED strings, managing up to 120W
  • Employs 3W LEDs to obtain 30W per string
  • Low voltage sensing circuitry
  • Logic level MOSFETs driven by the microcontroller without gate driver
  • High efficiency up to 98%
