Beschreibung

ICL8002G is a quasi-resonant PWM controller specially designed for high efficient offline LED driving application. It can be configured for different topologies such as flyback and buck converter. This demo board demonstrates its functions in dimmable LED bulb application with isolated flyback topology. Its quasi-resonant operation mode, primary side control, integrated PFC and phase-cut dimming control, and various protections make it an outstanding system solution for dimmable LED bulbs.Compared with ICL8001G demo board, the new ICL8002G demo board shows significant improvement in terms of dimming performance & output power and hence output current stability. The improvement in compatibility with TRIAC based phase cut dimmers has been achieved by adding damping and bleeding circuit blocks. The output power stability over a wide input voltage range has been increased by an additional line regulation circuit. Despite the additional circuit blocks the BOM still remains in a very competitive range.This demo board can be ordered with the sales code EVALLED-ICL8002G-B1.
