Switched-Inductor Power Supplies

This 55-page handbook uses insight to explain how inductors and transformers work and how switching power-supply microchips use them to transfer power. It discusses the applications that demand these switched inductors and the steps and precautions taken when implementing them with CMOS integrated circuits (ICs). It also details how ideal, asynchronous, and synchronous buck-boost, buck, boost, and flyback dc-dc converters operate, and how their voltages, currents, duty cycles, and conduction modes relate. Illustrative figures, equations, and examples complement discussions throughout.
