Analog wall dimmer for CFL/LED lamps based on the TS820 (USA version 110 V)

The STEVAL-ILD003V2 demonstration board is designed to propose a low-cost analog dimmer topology using a sensitive SCR TS820-600FP. The dimmer can drive typical low-consumption lamps, particularly CFL and LED dimmable lamps.

Through-hole technology is used for the most important components such as LC filter, gate resistor, turn-on delay capacitor, etc., in order to allow board modification, if needed.

The STEVAL-ILD003V2 eliminates flickering thanks to its continuous current applied through the sensitive SCR gate. This dimmer could easily replace a standard low-cost analog Triac light dimmer using a Diac-controlled circuit.

Key Features

  • Operation for 2-wire wall dimmer
  • Leading-edge control (compatible with all lamps commonly found on the market)
  • Operation on 120 V line rms voltage (98 to 132 V) and 50 Hz or 60 Hz line frequency
  • Dimmable power range with halogen, CFL and LED lamps (with 27 °C/W heatsinks mounted on SCRs12:
    • 3 to 350 W for 110/120 V rms line
  • Maximum operating ambient temperature:60 °C
  • Power efficiency @ 350 W / 120 V > 98.5%
  • Standby losses @ 120 V < 0.3 W (could be reduced to 0 if potentiometer features a mechanical switch to open the circuit at minimum setting)
  • RoHS compliant
  • Compliance with EMC standards
    • IEC 61000-4-4: criteria A for more than 4 kV
