Application note
250 W transition-mode PFC pre-regulator with the new L6563S
Introduction
This application note describes a demonstration board based on the new transition-mode 
PFC controller L6563S and presents the results of its bench evaluation. The board 
implements a 250 W, wide-range mains input PFC pre-conditioner suitable for desktop PCs, 
industrial SMPS, flat screen displays, and all SMPS having to meet the IEC61000-3-2 or the 
JEITA-MITI standard.
