This book begins with the premise that energy demands are directing scientists towards ever-greener methods of power management, so highly integrated power control ICs (integrated chip/circuit) are increasingly in demand for further reducing power consumption.
- A timely and comprehensive reference guide for IC designers dealing with the increasingly widespread demand for integrated low power management
- Includes new topics such as LED lighting, fast transient response, DVS-tracking and design with advanced technology nodes
- Leading author (Chen) is an active and renowned contributor to the power management IC design field, and has extensive industry experience
