2 Applications With High Efficiency and Thermal Requirement

Switching regulators are best known for their good efficiency. However, there are many power loss factors that contribute into the total losses; therefore, they impact the efficiency. To select the highest efficiency design, it is helpful to understand the basic mechanisms of power loss. This section explores some major power loss factors and discusses how to reduce their losses by making some design tradeoffs and choices.
