This application note describes a demonstration board based on the transition-mode PFC controller L6563S 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 L6563S is a current-mode PFC controller operating in transition mode (TM) and implementing an internal high-voltage startup circuitry.
This document describes a demonstration board (EVL6563S-100W) based on the L6563S transition-mode PFC controller. The board implements a 100 W, wide-range mains input PFC pre-conditioner suitable for ballasts, adapters, and flat-screen displays to meet IEC61000-3-2 or JEITA-MITI regulations. It operates with a line voltage range of 90 to 265 Vac and provides a regulated 400 V output.
| Line voltage range | 90 to 265 Vac |
|---|---|
| Regulated output voltage | 400 V |
| Rated output power | 100 W |
| Minimum switching frequency | 40 kHz |
| Maximum ambient temperature | 50 °C |
The minimum estimated efficiency is 92% at Vin = 90 Vac and Pout = 100 W.
The demonstration board is rated for a continuous output power of 100 W.
The board provides a regulated output voltage of 400 V.
The minimum estimated efficiency is 92% when the input voltage is 90 Vac and the output power is 100 W.
