Comprehensive resource on power management ICs affording new levels of functionality and applications with cost reduction in various fields. Design of Power Management Integrated Circuits is a comprehensive reference for power management IC design, covering the circuit design of main power management circuits like linear and switched-mode voltage regulators, along with sub-circuits such as power switches, gate drivers and their supply, level shifters, the error amplifier, current sensing, and control loop design. Circuits for protection and diagnostics, as well as aspects of the physical design like lateral and vertical power delivery, pin-out, floor planning, grounding supply guidelines, and packaging, are also addressed. A full chapter is dedicated to the design of integrated passives. The text illustrates the application of power management integrated circuits (PMIC) to growth areas like computing, the Internet of Things, mobility, and renewable energy. Includes numerous real-world examples, case studies, and exercises illustrating key design concepts and techniques. Power management integrated circuits (PMICs) are essential in today's electronic devices. They manage power delivery and consumption, provide efficient power supplies, and drive power switches that control actuators and motors. PMICs can be integrated into complex integrated circuits (ICs) or implemented as dedicated ICs. In this book, the term PMIC will refer to any type of power integrated circuit. The importance of PMICs has grown significantly in recent years, driving innovation and progress in various industries, from consumer electronics to automotive and industrial applications. With the progress of Machine Learning and Artificial Intelligence (AI), intelligent power management is critical to supplying complex processors and sensors.
