STEVAL-ILD004V1 Digital wall dimmer for halogen and low-consumption lamps Data brief Description The STEVAL-ILD004V1 evaluation board is designed to propose an innovative and low cost power topology for a light wall dimmer using two sensitive TS820-600FP SCRs and a single STGF10NC60KD IGBT to dim the following lamp types: 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 the STM8S103F2 microcontroller. Features Operation for 2-wire wall dimmer Leading-edge control only (compatible with all commonly-available lamps on the market) Operation at 110 V or 230 V line rms voltage and 50 Hz or 60 Hz line frequency Dimmable power range (higher power is possible with larger heatsink): 3 W to 600 W for 230 V rms line 3 W to 300 W for 110 V rms line Power efficiency 600 W - 230 V > 99% Standby losses 230 V < 0.3 W Short-circuit protection at startup Enhanced interface with push-buttons soft- start and soft-stop memory of last setting Compliance with EMC standards: IEC 61000-4-5: criteria A for 2 kV surge IEC 61000-4-4: criteria A for more than 2.5 kV Compliant with EN55015 with 600 W - 230 V halogen lamp RoHS compliant March 2015 DocID024136 Rev 3 1/4 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-ILD004V1 1 Schematic diagram Figure 1.
