描述 Description

The 2nd Generation Smart Ballast Control IC ICB2FL02G integrates all functions required to operate FL lamps such as preheat-, ignition- and run-mode and protection features. Digital mixed-signal power control is employed enabling speedy, cost-effective and stable ballast designs with a minimum number of external components. Reliable and robust high voltage isolation is achieved using Infineon’s proprietary Coreless Transformer Technology (CLT). The ICB2FL02G is functionally similar to the ICB2FL01G with a number of optimizations to operating frequencies and detection thresholds for dimmable ballast designs.
