Product details

Power Factor Correction (PFC), STMicroelectronics

Power Factor Correction (PFC) controllers operate in Transition Mode (TM) and Continuous Current Mode (CCM) for a wide-range-mains operation. The PFC controllers embed advanced protection features, which make SMPS more robust and compact, requiring fewer external components.
