Application note
100 W transition-mode PFC pre-regulator with the L6563S
Introduction
This application note describes a demonstration board based on the transition-mode PFC
controller L6563S and presents the results of its bench demonstration. The board
implements a 100 W, wide-range mains input, PFC pre-conditioner suitable for ballast,
adapters, flatscreen displays, and all SMPS having to meet the IEC61000-3-2 or the JEITA-
MITI regulation.
