STMicroelectronics Evaluation Board Power Management for STM8S103F2 for Halogen and Low-Consumption Lamps

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.

• 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
