The dimmer conduction phase controls the LED brightness. The LED brightness is modulated by PWM-dimming. The dimming frequency is selectable via product options. iW3610’s unique digital control technology eliminates visible flicker. iW3610 can operate with all dimmer schemes including: leading-edge dimmer, trailing-edge dimmer, as well as other dimmer configurations such as R-type, R-C type or R-L type. When a dimmer is not present, the controller can automatically detect that there is no dimmer. iW3610 operates in quasi-resonant mode ...
