iW3610: AC/DC Digital Power Controller for Dimmable LED Drivers
The iW3610 is a high performance AC/DC offline power supply controller for dimmable LED luminaires, which uses advanced digital control technology to detect the dimmer type and phase. 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.
