The Infineon digital fly back controller IC is a high performance microcontroller-based digital single-stage fly back controller with power factor correction for constant output current applications. The IC is available in a DSO-8 package and supports a wide feature set, requiring a minimum of external components. The digital engine offers the possibility to configure operational parameters and protection modes, which helps to ease the design phase and allows a reduced number of hardware variants in production. Accurate primary side output current control is implemented to eliminate the need for secondary side feedback circuitry.
