STEVAL-ILL038V2

The STEVAL-ILL038V2 is a LED resonant driver Evaluation Board that implements a 100W LED switched mode power supply (SMPS) based on the L6585DE. This device embeds a high performance transition mode (TM) power factor correction (PFC) controller, half-bridge (HB) controller and all the relevant drivers required to build a combo IC. The PFC section of this IC has superior performance in terms of harmonic content mitigation. High power factor (PF) and total harmonic distortion (THD) reduction are obtained as required by international standards, especially concerning universal input voltage operation. The TM PFC operation and highly efficient performance of the half-bridge topology provide very good overall circuit efficiency. In order to guarantee the maintenance-free operation required by this type of application during useful LED life, the board does not use electrolytic capacitors, these are replaced by safer film capacitors.
