ICL8105
Digital flyback controller IC for LED driver
The ICL8105 is a high performance configurable single-stage flyback controller with Power Factor Correction (PFC) for constant output current LED driver. The digital core of the ICL8105 and its advanced control algorithms provide multi operation modes such as quasi resonant mode, discontinuous conduction mode or active burst mode. With this functionality and smooth transition between the operation modes, the controller delivers high efficiency, high power factor and low harmonic distortion through the entire load range. The optional active burst mode control scheme significantly extends the dimming range and is aligned to the line frequency avoiding effects like flicker or shimmer while also reducing audible noise.
