Application note  
Digital constant-current controller for  
LED applications based on STM8S208X  
Introduction  
LEDs have been used for many years simply as status indicators but are now playing a  
considerable role in a host of application fields, even with high power requirements, due to  
improvements in lighting efficiency, longer lifetime, reliability, and costs. LED-based lighting  
systems are increasingly used in display panels, emergency lighting, architectural lighting  
and also backlighting.  
The growth of such systems is mainly due to new manufacturing technologies and  
innovations in this segment area, which probably represent the most important markets  
within the lighting field.  
The intent of this application note is to describe a new technique, based on a digital  
approach, performing a real average current-control on an LED streetlighting platform.  
A demonstration board, based on this approach, is orderable with the STEVAL-ILL031V1  
code.  
Further details are shown in STEVAL-ILL031V1 documentation.  
The LED streetlight platform has been developed on a DC-DC converter based on an  
“inverse buck” converter, creating advantages in terms of power switch control and  
conditioning signal circuitry for the current sensing.  
Moreover, performance, including cost performance, is also looked at.  
This solution has been customized for a streetlighting application but can be extended to  
many other fields.  
The advantages offered are in terms of low energy consumption, low maintenance, and a  
small and lightweight design.  
The real aim of this application note is to describe the average current-control methodology  
suitable for LED driving.  
The effectiveness of the control with the inverse buck's advantages is described on a  
dimmable platform, based on a multi-string system up to 120 W with independent current  
control. Two different kinds of dimming have been implemented: analog, also called linear  
dimming, and digital.  
The control has been implemented on the STM8S208RB microcontroller, [1] which is the  
best compromise in terms of cost and performance, validating an innovative current reading  
methodology.
