The ICL8001G employs quasi-resonant operation mode optimized for off-line LED lighting, especially dimmable LED bulbs for incandescent lampreplacement. Precise PWM generation enables primary control forphase cut dimming and high power factor PF>98%. Significant improved driver efficiency, up to 90%, compared to other conventional solutions. Ttheproduct has a wide operation range (up to 26V) of IC voltage supply and lower power consumption. Multiple safety functions ensure a full system protection in failure situations. With its full feature set and simple application, the ICL8001G represents an outstanding choice for quasiresonant flyback LED bulb designs combining feature set and performance at minimum BOM cost.
