In this video we will be having a look at a very versatile component, the TL431 IC. I used it in the feedback loop of my DIY switched mode power supply and thus got interested in it. That is why I will show you how it works, how you can use it in lot of different circuits and also how it functions in feedback loops of for example voltage converters. Let's get started!
