The Infineon digital PFC + fly back controller IC is a highly integrated next-generation device combining a multimode PFC plus a multimode FB with primary-side regulation. The integration of PFC and FB into a single controller enables reduction of external parts and optimizes performance by harmonized operation of the two stages. The two-stage approach divides the PFC responsibilities from the output current regulations functions. This ensures low variation in the output current to a non-visible level and allows for low THD, high power factor and a greater ability to withstand AC line perturbations.
