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.
