i W3616 AC/DC Digital Power Controller for High Power Factor Dimmable LED Drivers 1 Description The i W3616 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 i W3616 uses Dialog’s unique digital Flickerless TM technology to eliminate visible flicker in the entire dimming range and minimize low frequency output ripple current. With advanced dimmer detection technology, the i W3616 can operate with most wall dimmers including leading-edge dimmers (R-type or R-L type) and trailing-edge dimmers (R-C type). In addition, the i W3616’s cycle-by-cycle waveform analysis technology allows fast dimmer setting response. When no dimmer is on the line, the i W3616 optimizes the power factor and minimizes the current harmonic distortion to the AC line. The i...
