Development and challenges of high-efficiency highly-integrated power management integrated circuits
With the exponential growth of artificial intelligence's demand for computing power(electricity),high-performance computing chips have put forward strict requirements for power supply efficiency and density.High-density power management integrated circuits(ICs)have become a significant bottleneck that restricts the development of computing power and are an important factor in high-performance computing(HPC).For the power converter challenges of output power,density,and efficiency for HPC systems and the new power supply application scenarios for integrated chips systems,the traditional discrete power supply architecture and control technique are in urgent need of breakthroughs.Based on extensive discussion on the future development and key issues of integrated circuits at the latest forum organized by the National Natural Science Foundation of China,this paper summarizes the key issues and challenges in the development of power management ICs.This paper starts with the current development status of cutting-edge power supply technology for mainstream processors,discusses the long-term development trend of high-performance processor power supply technology,and gives development predictions for key technologies from the perspectives of power management system architecture,control technique,and passive components.
