The STEVAL-ILL066V1 demonstration board is a complete and configurable solution that manages a single high brightness LED string using the STLUX385A digital controller and two stages of power conversion. The application consists of a PFC regulator followed by a zero voltage switching (ZVS) LC resonant stage. The LED current is adjusted using a primary side regulation (PSR) control technique. The LED brightness can be dimmed by controlling the LED current down to a very low level. Communication interfaces like DALI and UART are present, as well as an insulated 0 - 10 control input. This application note describes the use of the STEVAL-ILL066V1 demonstration board, the hardware design and the firmware implementation. A real measurement is also described. For complete information on the STLUX385A digital controller, please refer to the STLUX385A datasheet。
