The dimmer conduction phase controls the LED brightness. The LED brightness is modulated by PWM-dimming. The i W3602-30C’s unique digital control technology eliminates visible flicker. The i W3602-30C can operate with all dimmer schemes including leading-edge dimmer and other dimmer configurations such as R-type, or R-L type. When a dimmer is not present, the controller can automatically detect that there is no dimmer. The i W3602-30C operates in a quasi-resonant mode to provide high efficiency. It offers a number of key builtin Features and uses advanced primary-side sensing technology to achieve excellent line and load regulation without secondary feedback circuitry. Additionally, its pulseby-pulse waveform analysis technology allows accurate LED current regulation. The i W3602-30C maintains stability over all operating conditions without the need for loop pensation ponents. Therefore, the device minimizes external ponent count, simplifies EMI design,...
