This application note describes a demonstration board based on the transition-mode PFC controller L6563H 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. The L6563H is a current-mode PFC controller operating in transition mode (TM) and implementing an internal high-voltage startup circuitry.
The document details an EVL6563H-100W demonstration board based on the L6563H current-mode PFC controller operating in transition mode. The design features a 100 W continuous power rating, wide-range mains input from 90 to 265 Vac, and a regulated 400 V output suitable for ballasts, adapters, and flat-screen displays.
