EVALLED-ICL8002G-B2

Evaluation board for dimmable 12W LED bulb in non-isolated buck topology ICL8002G is a quasi-resonant PWM controller specially designed for high efficient off-line LED driving application. This evaluation board illustrates the ICL8002G in dimmable LED bulb application using the non-isolated buck topology. The ICL8002G IC’s quasi-resonant operation mode, precise cycle-by-cycle peak current control, integrated PFC and phase-cut dimming control, and various protections make it an outstanding system solution for dimmable LED bulbs. The ICL8002G non-isolated bulb demo board shows high efficiency and power factor with single stage design. Damping and bleeder circuit blocks were added to achieve high compatibility with wide range of dimmers. The output current is well regulated over a wide input and output voltage range. Its compact form factor makes it easy to fit into many LED lamp shapes and sizes. Other available demo boards for ICL8002G are designed with isolated flyback topology. If galvanic isolation is not required, a non-isolated buck topology can be used with the following advantages:
