This book is an introduction to the topic of integrated power management systems. More specifically, it targets the battery powered systems on a chip that provide different functions such as wireless connectivity, sensing (e.g. temperature, pressure, movement), localization, processing, and more. Power management is a crucial part of such systems, as they must provide different power supplies, tailored to the requirements of each sub-block, and must maintain high efficiency in order to allow for a long battery life. The book covers the fundamental principles and guidelines needed to start the design of an integrated power management system, and an overview of practical techniques used in state-of-the-art implementations.

Technical topics include:

• Low-dropout regulators (LDO)


• Fundamental analysis and design techniques


• Overview of modern techniques


• Switching converters


• Inductive and capacitive DC–DC converters


• Steady state efficiency optimization


• Control techniques


• Low-power techniques


• Auxiliary circuits and system integration


• Voltage and current references


• Clock generators


• System interface.

It is ideal for fresh undergraduate and graduate students starting their careers, but also useful for experienced electronics engineers that are new to the power management domain and power electronics.
