Innovision Semiconductor Inc. Debuted with New Multiphase VRM Power Supply Scheme in the 2022 OCP CHINA DAY
Hosted by the OCP community and Inwave Information, the 2022 OCP CHINA DAY was successfully concluded in Beijing on August 10, 2022. In this exhibition, Innovision Semiconductor Inc. was invited to share the speech "New choice of multiphase VRM power supply scheme" in the Open Computing Ecology Forum, and Innovision Semiconductor Inc.'s new multiphase VRM power supply scheme debuted.
Innovision Semiconductor Inc.'s booth welcomed many visitors from the industry. The company's professional technical team and visitors carried out detailed product introductions and in-depth technical exchanges.
Multiphase VRM Power Supply Scheme
Wang Qing, senior sales manager of North China, said that in the field of today's open computing system hardware, the CPU is evolving towards lower process nodes, which brings more and more prominent problems of CPU power consumption and stray component loss. As a power chip company, if Innovision Semiconductor Inc. can improve the efficiency of the CPU VRM power supply with the largest energy consumption in the server system by 2%, it is equivalent to saving the power consumption of Google's data center for a year and promoting the construction and development of green data centers on technological innovation.
In addition to the rapid growth of the data center scale, the tense state of the semiconductor supply chain under the epidemic has not been effectively alleviated. One of the important reasons is that the VRM controller and Power Stage cannot be cross-applied, so the compatible design of power schemes has become the mainstream direction. In terms of Power devices, Innovision Semiconductor Inc. provides 70A Power Stage IS6806A/IS6809A compatible with the mainstream industry package under 12V application, using MCM package; In the low-current Power Stage field, JMW's IS6811A uses a single-wafer integrated design and achieves best-in-class efficiency and high-frequency performance over its competitors.
Innovision Semiconductor Inc. Scheme under 12V Main Line
For the ongoing Open Rack application, the evolution of power bus from 12V to 48V, Innovision Semiconductor Inc. also put forward its own views and corresponding research directions for 12V, 5V, and other intermediate buses.
8-phase controller -- IS6201A, with PMBus and SVI2 digital interface, based on the control mode of TCOTTM technology, has fast transient response-ability, and can dynamically adjust the number of working phases to optimize the overall efficiency, with accurate current sampling and reporting function, excellent Loadline linearity. With the Innovision Semiconductor Inc. 70A intelligent power level IS6806A/IS6809A, it can easily realize the stable power supply of more than 320A large current on the server, desktop motherboard, and other platforms.
IS6811A 35A intelligent power level in 1MHz, 2MHz switching frequency, peak efficiency and load efficiency beyond the international manufacturers, 160A peak current does not burn, with strong Robustness, 8 phase synchronous work can provide up to 200A supply current, suitable for notebook applications.
In the future, the development of open computing ecology will be inseparable from technological innovation. Innovision Semiconductor Inc. hopes to jointly explore "green, integration and empowerment" with industry partners, integrate more forces, and help promote the leading technology of data centers to move towards universality and low carbon.
