Power devices are mainly divided into power discrete devices and power management ICs. From the perspective of market share, power management ICs account for about 40%, while power discrete devices account for 60%. Both are widely used in various electronic products.
After many years of rapid development, the power management chips have slowed down in 2007 due to factors such as product inventory adjustments, slowing growth in usage, and falling product prices. It is expected that the 2007 China power management chips will be affected. The market growth rate will drop to about 15%. In recent years, the growth rate has dropped below 20% for the first time. However, due to the low market level in 2007 and the steady increase in future applications, the Chinese power management chip The market is expected to return to the 20% growth level in 2008.
From the point of view of the product type of the power management chip, the two most used products are still LDOs and DC-DC products, but these two types of products were affected by the price decrease and the slowing down of usage at the same time in 2007, in the power management chip. The market share in China dropped slightly. At the same time, thanks to the increased use of portable products such as mobile phones, the market growth rate of PMUs and battery management products is relatively high in 2007, and the market share of future PMUs, battery management, and hot-plugging products will increase. .
The power management chip is mainly used in fields such as computers, network communications, consumer electronics and industrial control. In addition, although the automotive electronics industry has a small market share, it is the fastest growing field. From the perspective of future development, the automotive electronics sector will continue to be the fastest growing sector and its market share will increase rapidly in the coming years. In addition, network communications will also continue to develop rapidly under the drive of 3G applications. The share will also steadily increase, and consumer electronics, computer and industrial control will be relatively stable.
In terms of technology, higher integration, higher power density, higher pressure resistance, current-carrying capacity, and higher energy efficiency have always been the development direction of power management chips, and the continuous updating and development of technologies will also be promoted. One of the major factors in the development of the power management chip market.
From the perspective of competition, in terms of power management chips, both in the market and in technology, European and American manufacturers have an absolute advantage, especially US manufacturers. Although the three European giants ST, NXP, and Infineon are also very competitive, the power management chips are just theirs. One of the many product lines, while the United States manufacturers have NS, TI, Fairchild, On Semiconductor, IR and Maxim and many other manufacturers, and more focused on the field of power management and manufacturers. The strong pattern of the power management chip market in Europe and America has continued for many years, and from now on, this pattern will continue in the coming years. Although European and American manufacturers maintain their advantages in technology and market, it does not mean that new entrants from China and other regions have no chance. At present, the technical threshold of low-end power management chips is not a problem for many capable design companies. In China, there are a group of companies engaged in the R&D of power management chips, such as Shengbang Microelectronics, Changyuntong, Longding, Mingwei, and China Resources Weiwei. Although the products are basically limited to LDOs, DC-DCs, and LED drivers, After all, they have achieved certain success in the market and objectively stated that these new entrants are currently unable to pose a significant threat to European and American manufacturers. They have clearly lagged behind leading manufacturers in terms of product line integrity and product technology, but these manufacturers are in power management. The chip's middle and low-end areas already have a certain degree of competitiveness. If it develops well in the future, it can compete with leading European and American manufacturers in certain fields and product applications.
Analysis of market trends of power device products in China
With the increasing demand for energy-saving products, more and more power devices such as power management chips and MOSFETs are being applied to the entire product, and the output of the entire machine is increasing and the proportion of power devices used in the entire product is increasing. Driven by this, China's power device market has maintained rapid growth in recent years. In the past five years, the compound growth rate of the market has reached 27.8%, which is a relatively rapid product development in the semiconductor products market.
