EVL6566B-40WSTB: 5V @ 2.4A, 12V @ 1.9A, 1.8V, 3.3 V

Summary

This document describes a demonstration board of a 40 W switch-mode power supply dedicated to set-top box, DVD and auxiliary SMPS for flat TVs or small size flat screen equipment.

The board accepts a wide range of input voltages (90 to 265Vrms) and delivers 4 voltages. The design is based on the L6566B, a new current mode fixed frequency or QR controller.

High efficiency and low standby consumption are the main characteristics of this board. These advantages, coupled with minimal part count required and low-cost approach of the global solution, make it a very interesting solution for powering digital consumer equipment, capable of meeting worldwide standby rules.
