Digital wall dimmer 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.

Key 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
