Introduction

STEVAL-ILL054V2 is a AC/DC LED driver evaluation board that offers an easy to evaluate and design LED applications. It is based on the STEVAL-ILL05x platform, which simplifies the design and reduces the number of external components thanks to its high integration level. It is designed to be the reference for a wide variety of LED driver applications. The board is compatible with nominal input voltages from 90 to 265 Vac, with a switching frequency of 20 kHz and a wide range of power and light flux power levels.

Application Fields and Working Principle

STEVAL-ILL054V2 can be applied to a variety of LED applications, including automotive, indoor and outdoor lighting, CCTV, amusement and gaming, touch panels and signage. The board can be easily configured with a PC interface by connecting the ST-LINK to any STM32F100 based optimized designs. The STEVAL-ILL05x platform has an integrated Constant-Flux and Constant-Temperature management system, which can be adjusted to meet the most demanding application requirements. The board consists of three sections: AC/DC front-end, control and LED output. In the AC/DC section, the STEVAL-ILL054V2 incorporates an AC/DC bridge rectifier, active PFC stages and EMI filters. In the control section, the on-board STM32F100 compatible processor resolves the complex dimming sequences of the LED driver. In the LED output section, the board features two smart LED modules that are optimized for efficiency and thermal management. A key feature of the STEVAL-ILL054V2 is its wide range of power levels and light flux. The constant current step-down converter based on a PCM (Power-Control Module) provides a wide range of power levels for the different application requirements. Moreover, the PCM incorporates an ideal current regulation profile offering an optimal light flux regulation to meet the requirements of the application.

Conclusion

In conclusion, STEVAL-ILL054V2 is an ideal evaluation board for a wide range of LED driver applications. With its wide range of power levels and light flux, the board is suitable for automotive, indoor and outdoor lighting, CCTV, amusement and gaming, touch panels and signage. The integrated Constant-Flux and Constant-Temperature management system is adjustable to meet the application’s demands and offer an optimal light flux regulation. Finally, the board can be easily configured with a PC interface by connecting the ST-LINK to any STM32F100 based optimized designs.
