New Trends in the Electronic World Power technology needs to be more efficient

At present, the power management chip technology is widely used in China. The development of power management chips is of great significance for improving overall performance. The selection of power management chips is directly related to the system requirements, and the development of digital power management chips is also facing high The cost of the problem. Currently, the power management industry is getting rid of the weak situation. According to HIS's survey of the power management market, it is estimated that the operating revenue of the global digital power market will increase to 12.4 billion U.S. dollars by 2017, more than triple the 2013 expected level of 3.7 billion U.S. dollars. Here, we invite Ms. Zhang Jieping, a marketing engineer in power management department from ADI Company, to talk about the market status and development trend of power management chips in detail.

1. In the face of increasingly stringent power efficiency requirements, do you think semiconductor manufacturers can help improve the power conversion efficiency of the power system?mobile power plant

Green energy is the demand in today's industrial chain, to enhance efficiency has become the goal of upstream and downstream manufacturers. Semiconductor manufacturers are striving to improve their devices by, for example, reducing static power consumption and reducing light-load power consumption with new control technologies. They improve overall efficiency by integrating features such as power devices that dynamically regulate output voltage by sensing the system's operating state To achieve the purpose of optimizing the efficiency of the power devices in terms of process improvement to improve efficiency. A variety of enhancements are made due to the concept of green energy to make due efforts.

2. How do you view the current trend of power management technology development, the future power management system how to deal with changes in market demand and harsh requirements?

With the rapid development of 3G technology, the construction of a new generation of base stations and data centers in the financial and telecommunications networks also places higher demands on the power management system. At the same time, large-scale popularization of 3G technology communication networks, increasing concentration and increasing data volume transfer require that power suppliers must increase their investment in innovative technologies and improve their energy-efficient performance. Through the introduction of high value-added products or solutions to save users the investment cost, while ensuring the stability and efficiency of the operation, in order to fully protect the user experience. Green, environmental protection, energy saving has been the focus of power management system technology innovation in recent years. With the continuous infiltration of green technologies in various industries, new industry standards are also driving product upgrades.

Lighting, telecommunications, smart grid, smart appliances and other fields also have huge room for growth, but also the direction of the focus of power companies. Energy-saving is mainly reflected in the energy-saving power products and the overall energy-saving room, and "green" is mainly reflected in improving the efficiency of the machine to reduce the interference to the power grid and save space and save costs.

In addition, the module power, networked power is also the current focus. Modular power supply, in addition to improving the reliability of the power supply, the company itself can also be based on electricity load matching module. Therefore, manufacturers who want to maintain or even increase their market share in the fierce market competition, continuous technology and product innovation is the top priority. For the power industry chain, the development of standardized universal power supply has been quite mature, but efficient, energy saving, miniaturization, high power density is still the focus of a new generation of products. For the power market segments, such as medical, industrial, automotive, energy, consumer, etc., power supply companies will be combined with the system application, the development of system-specific power, which will be one of the future development goals of power companies.

3. In addition to technology, in order to succeed in the power management market, what are the elements?

Power management technology providers have not only limited to the power technology itself, but need to combine the power supply and system knowledge better, and develop better performance and application products for system applications. For example, for wired applications, as optical fiber transmission speed increases, for example, at 30G and 100G, higher requirements are imposed on the bandwidth of the noise, and the bandwidth of the noise suppression required by the LDO increases accordingly. In the application of radio frequency, because of the increase of the transmitting and receiving channels, put forward the new demand in the power of the power, noise, so need the power company to understand the application, develop more suitable products of the application.
