STMicroelectronics Evaluation Board Potentiometer Dimmer for STF17N62K3

Trailing Edge Phase Control Rotary Wall Dimmer, STMicroelectronics

The STEVAL-ILD005V1 Evaluation Board implements a simple reverse phase cut dimming solution for analogue wall dimmers. A pair of STF17N62K3 power MOSFETs are used. The AC analogue control dimming allows for both on/off power switching and up/down dimming functions through a single linear rotary potentiometer equipped with a mechanical switch.

• Operation for 2-wire wall dimmer
• Trailing-edge control only (compatible with either resistive or capacitive lighting loads)
• Operation on 230V RMS mains voltage 50/60Hz
• Dimmable power range from 40W to 300W
