Transformers are widely used to efficiently transfer both power and data in switching power supplies, MOSFET gate drivers, and isolation circuits. Because they come in what can be a bewildering array of sizes and configurations and are often characterized with unfamiliar terms, they can be confusing to the uninitiated.

But fear not! All transformers work from the same fundamental principles, so we've assembled this e-Book to help you find the right transformer for many common applications.
