It appliesadvanced digital control technology to detect the dimmer type,enabling it to provide dynamic impedance to interface with the dimmer and to control the LED brightness at the same time. With advanced dimmer detection technology, the iW3688 can operate with most wall dimmers including leading- Edge dimmers (R-type or R-L type), trailing-edge dimmers(R-C type), and smart dimmers. In addition, the iW3688's cycle-by-cycle waveform analysis technology allows for fast dimmer transient response. In no-dimmer mode, the iW3688 operates the main powerconverter that delivers current to the LED load in quasi- resonant mode to provide high power efficiency and lowelectro-magnetic interference (EMI). When there is no dimmer on the line, the iW3688 optimizes the power factorand minimizes the current harmonic distortion to the AC lineThe commonly utilized converter topologies for iW3688 arebuck-boost and flyback. The iW3688 uses patented PrimAccurate™ primary-sidesensing technology to achieve excellent LED currentregulation under different AC line and LED load voltages,without using a secondary-side feedback circuit and thus eliminating the need for an opto-coupler. The iW3688 minimizes the external components count bysimplifying the EMI filter with Dialog's EZ-EMI technologyand by integrating current sink, switching, and Vcccharging circuit. Additionally, the iW3688 does not requirean auxiliary winding, which eliminates the need for a custominductor. The digital control loop of the iW3688 maintainsstability over all operating conditions without the need forloop compensation components. The iW3688 maintains high performance wide-rangedimming and achieves excellent dimmer compatibility with asimple application circuit. 3.0 ApplicationsDimmable LED retrofit lamps up to 20WDimmable LED luminaires up to 20WAny items you need, please send the BOM List to us, we will for sure to supply you not only with new and original products but also the best service by our professional team who are with us since our head office in Shenzhen was set up in 2009!
