Power Management Integrated Circuits

This book intends to be a comprehensive text on the topic of integrated circuits for power management, putting together both theoretical foundations and practical details, leading to successful design practices in research and industry. It covers all the three main categories of power management circuits, viz., linear regulators, inductor-based switchers and switched-capacitor circuits, and presents detailed discussion of their common topologies, operation and modeling.

Features

• Includes underlying theory and design/implementation practical ingredients for power management integrated circuits (PMICs).
• Provides in-depth analysis of topologies and circuits related to linear regulators, switched-capacitor converters and inductor-based converters.
• Covers all the relevant topics at the intersection between power electronics and integrated circuit design areas.
• Provides guidelines for design of circuits and solutions for all the pertinent topologies.
• Indicates all important issues and the related trade-offs in the design of PMICs.

The book will be a valuable resource for senior- and graduate-level students as well as industry professionals who have done university-level courses on analog circuit design, control systems and power electronics.
