DC/DC Buck Converters: What do all of these features mean?

As switching converters have evolved, they have taken on a host of new features to operate more efficiently and quietly. To some, however, all these new features listed on the front page of the datasheet may seem foreign. This training series dives into those features to explain the true benefits of each and help you decide which are necessary for your power supply design. Specifically covered in this series are the buck converter topics of:

  • Common features like UVLO, Enable, Soft Start, and Power Good
  • Mode of operation, like PFM, hiccup, and current limit
  • Minimum off-time and on-time
  • Quiescent current

1. Buck Converter Features: Explained

The features list on the front page of your new DC/DC buck converter datasheet may contain a number of common, familiar terms along with some that are maybe... not as common. The following training videos will introduce you to many of the features, explain why they are important, and show you how to utilize them to improve the performance of your power supply design.
