Description
The ICL8001G employs quasi-resonant operation mode optimized for off-line LED lighting, especially dimmable LED bulbs for incandescent lamp replacement.
Precise PWM generation enables primary control for phase cut dimming and high power factor PF>98%. Significant improved driver efficiency, up to 90%, compared to other conventional solutions. Tthe product 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.
