Shenzhen Guowei


Shenzhen Guowei Electronics Co., Ltd., established in 1993, was the first integrated circuit design company to launch under China’s national “909” Project. The company primarily focuses on the R&D, production, testing, and sales services of specialized integrated circuits. Its product portfolio spans seven major series, including microprocessors, programmable devices, memory chips, network buses and interfaces, analog components, SoPC system devices, and custom-designed chips. Following a successful restructuring at the end of 2012, the company was listed on the stock market and is now part of Tsinghua Unigroup’s publicly traded subsidiary, Tsinghua Unigroup Microelectronics. With an experienced R&D team boasting extensive chip-design expertise, Guowei has already achieved breakthroughs in verifying SoPC designs at the billion-gate level, while also establishing a robust platform for designing, testing, and validating CMOS products manufactured using processes below 14nm ultra-deep sub-micron technology. The company’s products cater to diverse industry needs and have forged strategic partnerships with several leading domestic enterprises across various sectors, earning widespread market recognition and a solid reputation.

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.
