iW3617 AC/DC Digital Power Controller for High Power Factor Dimmable LED Drivers 1 Description The iW3617 is a two-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires.
It applies advanced digital control technology to detect the dimmer type and phase, which provides dynamic impedance to interface the dimmer and control the LED brightness at the same time.
The iW3617 uses Dialog’s unique digital FlickerlessTM technology to eliminate visible flicker in the entire dimming range and minimize low frequency output ripple current.
With advanced dimmer detection technology, the iW3617 can operate with most wall dimmers including leading-edge dimmers (R-type or R...
