This first video of a six video series gives on overview on the basic non-isolated converter topologies. It shows which converter topologies can be derived from the inverting buck-boost converter. The focus is then on the most popular 2 topologies out of this list: flyback and SEPIC. When you have viewed this video, you should know when a flyback converter is a good choice for your power supply and when the SEPIC gives you a better result.
