Offline LED Controller For PFC And Dimming With Integrated 800 V CoolMOS®

The ICLS8082G employs a quasi-resonant operation mode optimized for off-line LED lighting, especially for dimmable LED bulbs for replacement of incandescent lamps.

Precise PWM generation enables primary control for phase-cut dimming and high power factors (PF) > 98 %. It offers significantly improved driver efficiency, up to 90 %, compared to other conventional solutions. The product has a wide operation range (up to 26 V) of IC voltage supply and lower power consumption. Multiple safety functions ensure full system protection in failure situations.

With its full feature set and simple application, the ICLS8082G represents an outstanding choice for quasiresonant flyback LED bulb designs combining the feature set and performance at minimum BOM cost.
