Overview
The STMicroelectronics L6563TR is an advanced transition-mode Power Factor Correction (PFC) controller. This device operates in Transition Mode (TM) and is designed to improve performance and reduce distortion in mains current. It features a highly linear multiplier and a special correction circuit to minimize crossover distortion, allowing for wide-range mains operation with extremely low Total Harmonic Distortion (THD) even over a large load range. The L6563TR is part of the L6563 series and is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) package.
