With the progress of the times and the development of science and technology, modern electronic equipment generally tends to be portable, miniaturized, and multifunctional. To achieve these requirements and ensure the normal use of electronic equipment, it is necessary to have a stable and sufficient current. Since the advent of the transistor in the 1940s, the development of power management has kicked off, and it has become more and more mature.
What is power management? The data indicates that the effective distribution of power to the different components of the system. And how to allocate, this is the role of the power management system. A good power management system can accurately distribute current, reduce energy consumption when components are idle, and extend battery life several times. It can be said that there are many related technologies, including modern electronics, network construction, and power conversion.
The advent of transistors created power management technology. The development of integrated power electronic technology in the 1980s brought power management into a new era, covering industries, transportation, information communications, aerospace, defense education, culture and other fields. The power management chip is the product of power management technology.
In recent years, the domestic power management chip market has maintained rapid growth. Data show that in 2012, it reached 43.068 billion yuan, and in 2018 it has reached an astonishing 68.153 billion yuan. With the birth of high-end industries, electric vehicles, artificial intelligence and other fields, the scale of the power management chip market will only exceed that. Zhongshan Industrial Research Institute predicts that my country's power management chip market will reach 78.1 billion yuan in 2020.
However, in such a huge market, domestic chips have to rely on imports. In order to change this situation and promote the development of this field, the State Council recently issued "Several Policies to Promote the High-quality Development of the Integrated Circuit Industry and Software Industry in the New Era". The document stated that it is necessary to strengthen the research and development of core technologies in the fields of integrated circuit design tools, integrated circuit key materials, integrated circuit equipment and process technology, and high-end chips.
Many companies are aware of the demand for high-end chips and are taking action. Jiehuate Microelectronics (Hangzhou) Co., Ltd. (hereinafter referred to as Jiehuate) has set the goal of "developing an excellent battery management system" on the road of power management chip research and development, and strive to realize it in the future.
It is reported that Jetwater was established in March 2013. The company's business is: to provide system solutions and product services for users in the power, communications, and electric vehicles industries. At present, in addition to R&D power management chips, Jiehuat also produces battery management, LED lighting, DC/DC converters and other products.
According to investigation and analysis, the future power management chip will develop in the direction of high efficiency and low consumption, core digitization, intelligence, and integration. Among them, high efficiency and low power consumption are always one of the core indicators, that is, improving the power conversion efficiency and reducing standby power consumption. As future systems become more complex, only continuous upgrades of power management chips can meet demand.
