Klappentext zu „Integrated High-Vin Multi-MHz Converters “
This book provides readers with guidelines for designing integrated multi-MHz-switching converters for input voltages/system supplies up to 50V or higher. Coverage includes converter theory, converter architectures, circuit design, efficiency, sizing of passives, technology aspects, etc. The author discusses new circuit designs, new architectures and new switching concepts, including dead-time control and soft-switching techniques that overcome current limitations of these converters. The discussion includes technology related issues and helps readers to choose the right technology for fast-switching converters. This book discusses benefits and drawbacks in terms of integration, size and cost, efficiency and complexity, and enables readers to make trade-offs in design, given different converter parameters.- Describes a study for increasing switching frequencies up to 30 MHz at input voltages up to 50V or higher in the scaling of the size of switching converter passives;
- Analyzes various buck converter implementations and shows that a preference due to higher efficiency depends on the operating point, on the available switch technologies, and on the implementation of the high-side supply generation;
- Describes an efficiency model based on a four-phase model, which enables separation of loss causes and loss locations.

Autoren-Porträt von Jürgen Wittmann
Jürgen Wittmann received his Dipl.-Ing. degree from the Technical University Munich, Germany, in 2006. From 2006 to 2011, he was with the Mixed-Signal Automotive business unit of Texas Instruments in Freising, Germany. He designed ICs for automotive applications such as power management, network transceivers, gate drivers, motor control, with focus on low-power, EMC, ESD. In 2011, he joined the Robert Bosch Center for Power Electronics at Reutlingen University as a research assistant, working towards his Dr.-Ing. degree in the area of power- and microelectronics with the focus on integrated fast-switching, high-Vin DC-DC converters. He holds four patents, and received the Best Paper Award at ESSCIRC 2015. In 2017, he was invited to give an ISSCC forum presentation on integrated voltage regulators for SoC and emerging IoT systems. Jürgen Wittmann is currently with Dialog Semiconductor, Germering, Germany, where he is working as technical project lead for power management ICs in mobile devices.
