Product Overview

Trailing edge phase control rotary wall dimmer based on STF17N62K3 power MOSFET. This evaluation board implements a simple and cost effective MOS based reverse phase cut dimming solution for analogue 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. The AC analogue 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 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.
  • Operation for 2-wire wall dimmer
  • Trailing-edge control only (compatible with all lamps commonly found on the market)
  • Operation on 110V or 230V rms line voltage (±10%) and 50Hz or 60Hz line frequency
  • Dimmable power range (without heatsinks mounted on MOSFETs)
  • Maximum operating ambient temperature 50°C
  • Power efficiency at maximum power 230V is >95%
  • Power factor at maximum power is > 0.98
  • Control and regulation interface with a switched type single linear rotary potentiometer
  • IEC 61000-4-5: criteria A for 2KV surge, compliant with EN55015 with 300W-230V halogen lamp
  • Flicker-free dimming performance, low inrush current generation
