Overview
The L6562ADTR, produced by STMicroelectronics, is a current-mode Power Factor Correction (PFC) controller operating in Transition Mode (TM). This device is designed to optimize power factor and reduce total harmonic distortion (THD) in power supply systems. It features a proprietary multiplier design that minimizes AC input current distortion, allowing for wide-range mains operation with extremely low THD even over large load ranges. The L6562ADTR is particularly suited for applications requiring high power factor and compliance with international standards such as IEC61000-3-2.
