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.
