+ - 15 volt supply

[Rob]

I had always thought that a switcher just dealt with the front end of the
signal, then, the switched signal is fed to a 78xx or ua723 where it is
regulated.. Well, at that point, where does the issues that define the
differences between a switcher and a regulated supply?

This has always confused me..
