Switching regulators are increasing in popularity because they offer the advantages of higher power conversion efficiency and increased design flexibility (multiple output voltages of different polarities can be generated from a single input voltage).
This paper will detail the operating principles of the four most commonly used switching converter types:
Also, some multiple-transistor converter topologies will be presented:
Application information will be provided along with circuit examples that illustrate some applications of Buck, Boost, and Flyback regulators.
