Dialog Semiconductor iW3689
The iW3689 is a single-stage, high-performance AC/DC off-line power supply controller for dimmable LED luminaires. It applies advanced 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 iW3689 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.| Part No. | iW3689 |

DESCRIPTION
In addition, the iW3689’s cycleby-cycle waveform analysis technology allows for fast dimmer transient response. In no-dimmer mode, the iW3689 operates the main power converter that delivers current to the LED load in quasiresonant mode to provide high power efficiency and low electro-magnetic interference (EMI). When there is no dimmer on the line, the iW3689 optimizes the power fa
