I still wonder why we don't see more high-frequency switchers.
We do. Computers now use switching supplies, as do a lot of "wall warts" and also many electronic devices. It's the old analog regulators that are now, fortunately, getting scarce. Your PC would be a lot heavier if it didn't have a switching supply.
Yes, but that tower under my desk could have a switcher PSU a fraction the size/weight it does. I know, I've built them! So, the question is "why?" Is there some weir economics or is it 'history' ? -- Bullet proof vest vendors do not need to demonstrate that naked people are vulnerable to gunfire. Similarly, a security consultant does not need to demonstrate an actual vulnerability in order to claim there is a valid risk. The lack of a live exploit does not mean there is no risk. - Crispin Cowan, 23 Aug 2002 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
