XDPS2221E Description
The XDPS2221E PWM controller is a highly integrated device bining a multimode AC-DC PFC controller and a multimode DC-DC hybrid-flyback controller supporting wide output voltage range designs. The integration of PFC and hybrid-flyback into a single package enables the reduction of external bill of material ponents and optimizes the system performance by harmonized operation of the two stages.
