  • The STEVAL-ILD005V1 evaluation board implements a simple and cost-effective MOS-based reverse phase cut dimming solution for analog wall dimmers using a pair of STF17N62K3 power MOSFETs controlled by a triple 3-input NOR gate to effectively dim either resistive or capacitive lighting loads (i.e. halogen lamps, electronic low voltage transformers and various dimmable CFL/LED lamps). The AC analog control dimming technique employed allows for both on/off power switching and up/down dimming functions through a single linear rotary potentiometer equipped with a mechanical switch which opens the circuit at minimum setting. Control of the board is achieved using a triple 3-input NOR gate (pin-to-pin compatible with a ST's HCF4025BE 14-lead dual in-line CMOS gate logic device in plastic SO-14 micropackage) which acts as a gate driving voltage signal source, performs zero crossing detection and timing through the use of a few other passive components and diodes.

    Key Features

    • Operation for 2-wire wall dimmer
    • Trailing-edge control only (compatible with all lamps commonly found on the market)
    • Operation on 110 V or 230 V rms line voltage (±10%) and 50 Hz or 60 Hz line frequency;
    • Dimmable power range (without heatsinks mounted on MOSFETs)
      • 40 W to 300 W for 230 V rms line
      • 15 W to 90 W for 110 V rms line
    • Maximum operating ambient temperature: 50 °C
    • Power efficiency @ Max power - 230 V > 95%
    • Power factor @ Max power > 0.98
    • Control and regulation interface with a switched type single linear rotary potentiometer
    • Compliance with EMC standards:
      • IEC 61000-4-5: criteria A for 2 kV surge
      • Compliant with EN55015 with 300 W - 230 V halogen lamp
    • Flicker-free dimming performance
    • Smooth dimming operation and silent dimming control with no buzzing or audible noise
    • Acceptable levels of EMI noise without the need for LC filters to reduce conducted emission disturbances
    • Low inrush current generation
    • RoHS compliant
