The STEVAL-ILL017V1 is an evaluation board developed by ST Microelectronics that is specifically designed for LED drivers. It is based on a dedicated MCU and also includes a graphical user interface (GUI) to help customers quickly evaluate and test the features and other features of the board. Additionally, the board also features various configurable components to simplify customization of the board.

The board features two Application Modes: a Dynamic Current Control Mode, which is optimized for lighting applications, and a Triac Control Mode which is more suitable for managing the dimming level of an AC line powered LED driver. The application field of this board covers a wide range of applications such as signage, street lighting, and automotive applications. The board also offers a wide range of additional features including a high power boost, overvoltage protection, overcurrent protection, current sensing and an active frequency modulation (AFM) mode.

The working principle of this board is based primarily on the PIC16F1936 microcontroller and the associated hardware features. When the board is powered up, it will start the driving process and then set the output current according to the needed application. This is done via a digital potentiometer and a transconductance amplifier which serve as the power control components. The output current and current sensing is monitored and controlled, allowing the board to adjust its working parameters in response to changing power requirements or feedback from sensors, enabling optimal performance and maximum efficiency.

In the Dynamic Current Control Mode, the board utilizes a Pulse Width Modulation (PWM) signal to control the output current. This also allows for precision current regulation and also enables the board to adjust the current in small, incremental steps for maximum efficiency. The output voltage is regulated and held constant by an external voltage regulator, and the board can also provide overload protection and temperature protection. In the Triac Control Mode, the board is used to regulate the dim level of an AC line powered LED driver. In this mode, the board will adjust the current to maintain the desired dim level, while still providing maximum efficiency.

The STEVAL-ILL017V1 evaluation board provides an easy-to-use and cost-effective platform for testing and evaluation of LED drivers and related applications. Thanks to the dedicated MCU, graphical user interface and configurable components, users can quickly and efficiently evaluate, customize and debug their projects. This board also features various protection features, enabling it to provide robust and reliable performance in a wide range of applications.
