7 Find your way in electronics with TI power rulers Whether you re an experienced design engineer or not, electronics is a vast and complex subject, and you probably often wish you could get a helping hand on some topics you re less familiar with or last encountered several years ago. That s where TI s Power Rulers and their application report can help make your life as a designer easier. You can use them not only in power but also in many other areas of electronics. TI power rulers provide important rules of thumb and many approximate values. While they are sufficient for a first estimate, the use of more accurate numbers and equations should be considered when exact results are required.
