Flyback converters store energy in the inductor during the transistor ON interval, and transfer that energy to the load storage capacitor during the OFF interval, such that output voltage magnitudes greater than the input voltage can be achieved.

WebFeb 20, 2024 · There is another version of a buck-boost converter known as a flyback converter. Here, the inductor is split to form a transformer. So, voltage ratios of primary and secondary windings of the transformer are multiplied, but there is one more advantage of this circuit: isolation (more technically, galvanic isolation). http://www.kynixsemiconductor.com/News/42.html
