Infineon, Resonant Controller 20-Pin, PG-DSO-19 ICL5102HVXUMA1

The Infineon PFC + Resonant half-bridge controller is a highly integrated multi-mode PFC and resonant HB combination controller. The integration of PFC and HB into a single controller enables reduction of external components 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 voltage and current and allows for low THD, high power factor and a greater ability to withstand AC line perturbations. The multi-mode operation of PFC converter provides excellent efficiency over the whole load range.
