Hi Robert, very good point, one more issue is the number of components used. On switchers, this is easily 10x to 15x the number of components used on a simple linear supply. Every component and it's solder-joints are a statistical sources of failure. bye, Said In a message dated 6/1/2009 12:46:36 Pacific Daylight Time, [email protected] writes:
Most switch mode power supplies actually run a voltage doubler on the input when running on 110V. This puts over 300V across the transformer and switch. Also the regulation loop crosses the isolation barrier introducing more failure points that can result in overvoltage.
