Aerospace Research Institute 771


The Xi'an Institute of Microelectronics Technology (also known as Lishan Microelectronics Company, Xi'an Institute 771, and the 771st Research Institute of the Ninth Academy, China Aerospace Science and Technology Corporation) is affiliated with the Ninth Academy of China Aerospace Science and Technology Corporation. It specializes in the research, development, mass production, and testing of cutting-edge technologies across three key fields: computers, semiconductor integrated circuits, and hybrid integration. As the nation’s sole large-scale, specialized institute integrating research, development, and manufacturing in these three critical areas—computers, semiconductor ICs, and hybrid integration—it also served as the founding entity of ZTE Corporation, one of the world’s top 100 IT companies. Moreover, the institute has been a pioneering force and a leading contributor to China’s aerospace microelectronics and computing industries. Established in October 1965, the Xi'an Institute of Microelectronics Technology has earned numerous prestigious awards, including multiple National Special Prizes for Scientific and Technological Progress and National Defense Special Prizes for Scientific and Technological Advancement. The institute has also received accolades such as the National May Day Labor Medal, the Outstanding Contribution Award for High-Tech Equipment Development Projects, the Outstanding Contribution Unit for China’s Chang’e-2 Lunar Exploration Mission, the Shaanxi Provincial Advanced Collective Award, and the Shaanxi Provincial Civilized Unit Vanguard Title.

How to Use a Multiphase Boost Converter

When the required system voltage exceeds the available supply voltage, a boost converter is typically an ideal solution. However, conventional standard boost topologies are not the only option. In certain application scenarios, phase-shifted multiphase boost converters can deliver superior performance: these converters achieve higher efficiency under heavy-load conditions while significantly reducing the required capacitance values for both the input and output stages.
