L6562A Transition-mode PFC Controller IC (SMD Package) Digital Amp Meter Gold for these 430E resistorsThe L6562A is a current mode PFC controller that operates in Transition Mode (TM). It delivers better performance while having the same pin out as its predecessors, the L6561 and L6562. The very linear multiplier has a unique circuit that can lessen the distortion of the AC input current and enable wide range mains operation with a very low THD, even over a wide load range. A voltage mode error amplifier and a precise (1 percent @TJ = 25C) internal
