After five months of intense competition, the award list for "Core China 2022" has been released, and Changgong Micro's highly integrated parallel synchronous buck converter has won the "2022 Most Valuable Market Project Award".
In recent years, China's self-sufficiency rate for integrated circuits has been on the rise and is expected to reach 19.6% by 2022. However, despite this progress, there remains significant room for domestic substitution. With the emergence of new computing fields such as the Internet of Things and artificial intelligence in China, there is a growing need for independent research and development of high-precision, high-efficiency low-voltage and high-current power modules. Based on the market for CPU and GPU localization, there is a need for independent research and development of high-precision, high-efficiency power management chips that operate at low voltage and high current levels.
The IS6608A is a fully integrated, PMBUSTM-compatible high frequency synchronous buck converter, which adopts multiphase parallel technology and can support up to 8 chips in parallel to achieve a peak output current of 280A. IS6608A is faster than foreign chips in transient response, excellent dynamic phase management technology (automatic up and down phase) and comprehensive telemetry digital communication function, greatly improving the efficiency and convenience of the chip.
The IS6608A uses the PMBus3.1 interface for device operation setup and detection, with internal LDO bias and external bias, which further improves efficiency. An accurate differential detection scheme and an accurate internal reference voltage of 0.6V±1% contribute to good linearity and load regulation over the temperature range.
IS6608A highly integrated protection function: overcurrent protection, negative overcurrent protection, overvoltage protection, undervoltage protection and overtemperature protection, support four frequency programmable (400kHz, 600kHz, 800kHz, 1MHz), mainly used in industrial, communication, computing power supply and other markets.
As the first domestic multiphase parallel power chip that can supply CPU power,Innovision Semiconductor Inc. IS6608A has broken the technical monopoly of European and American power chip manufacturers in the multiphase power supply, filled the gap in the domestic market, and helped "China Core" with an international vision and first-class quality.
