STMicroelectronics STEVAL-ILD005V1 Eval Board Rotary Wall Dimmer

STMicroelectronics STEVAL-ILD005V1 evaluation board implements a simple and cost-effective MOS-based reverse phase cut dimming solution for analog wall dimmers. It uses 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 analog control dimming technique employed allows for both on/off power switching and up/down dimming functions. A single linear rotary potentiometer equipped with a mechanical switch opens the circuit at the minimum setting.
