AN-556 Introduction to Power Supplies
... The three previous regulators are suitable for low voltage control when no electrical isolation is required. However in off-line switchers operating from 110V/220V mains, electrical isolation is an absolute must. This is achieved by using a transformer in place of the inductor. The flyback converter ...
