In this video I will be showing you how I created a synchronous buck converter. Such a synchronous design comes with one big advantage and that is a better efficiency. Datasheets claim an efficiency of 95% and above which I wanted to confirm by myself. That is why I will not only show you how a normal buck converter functions, but also how to transform it into a synchronous buck converter. Let's get started!
