This application note is the second of a two-part series on Switch Mode Power Supply topologies (SMPS). The first application note in this series, AN1114 - Switch Mode Power Supply (SMPS) Topologies (Part I), explains the basics of different SMPS topologies, while guiding the reader in selecting an appropriate topology for a given application. Part II of this series expands on the previous material in Part I, and presents the basic tools needed to design a power converter. All of the topologies introduced in Part I are covered, and after a brief overview of the basic functionality of each, equations to design real systems are presented and analyzed. Before continuing, it is recommended that you read and become familiar with Part I of this series.
