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 managementIncludes new topics such as LED lighting, fast transient response, DVS-tracking and design with advanced technology nodesLeading author (Chen) is an active and renowned contributor to the power management IC design field, and has extensive industry experienceAccompanying website includes presentation files with book illustrations, lecture notes, simulation circuits, solution manuals, instructors’ manuals, and program downloads
