Infineon Technologies ICL8082G

Description

The ICL8001G / ICLS8082G employs a quasi-resonant (QR) operation mode and, due to the availability ofoutstanding PFC performance, is optimized for off-line LED lighting applications such as dimmable LED bulbs forincandescent lamp replacement, LED downlights and LED tubes in a power range from typically 5 W to 50 W.Precise PWM generation enables primary control for phase cut dimming and potential for high power factors ofPF > 99 %. Depending on the power class, significantly improved driver efficiency of up to 91 % is feasible. Theproduct has a wide operation range of IC voltage supply and low power consumption. Multiple safety functionsensure full system protection in failure situations. With its full feature set and simple application, the ICL8001G /ICLS8082G represents an outstanding choice for QR flyback designs combining feature set and performance ata minimum BOM cost.
