The STEVAL-ILD004V2 evaluation board represents an innovative and low cost power topology for light wall dimmers using two sensitive TS820-600FP SCRs and a single STGF10NC60KD IGBT to dim 100 - 240 V halogen lamps, SELV halogen lamps through magnetic or electronic transformers, and new CFL and LED dimmable lamps. Control of the board is achieved with STM8S103F2 microcontroller.
In comparison with STEVAL-ILD004V1, this board introduces a buck SMPS (operated through the VIPer06XS) instead of a linear power supply, for compatibility across all dimmable LED and CFL lamps.
