Application note
250 W transition-mode PFC pre-regulator with the new L6563H
Introduction
This application note describes a demonstration board based on the new L6563H transition-
mode PFC controller and presents the results of its bench evaluation.The board implements
an 250 W, wide-range mains input PFC pre-conditioner suitable for desktop PCs, high
power adapters, flat screen displays, and all SMPS having to meet the IEC61000-3-2 or the
JEITA-MITI regulation.
The L6563H is a new current-mode PFC controller operating in transition mode (TM) and
implementing an internal high voltage startup circuitry.
