Application for portable power management is becoming a dazzling bright spot in the semiconductor field. According to market research firm CIR's market report points out that within the next few years based on the application of portable power devices is very optimistic about the laptop battery market prospects, the 2004 sales revenue is expected to reach 4.3 billion U.S. dollars, and in 2008 rose sharply to 7.2 billion U.S. dollars.

Portable devices in the growing of new features, power management will create substantial new demand. At the same time, portable device manufacturers are facing increasing pressure, they inspiron battery need to integrate these functions is shrinking in size, at the same time to maintain it longer working hours.

For example, with the arrival of 3 G, cell phones not only to visit the website, send e-mail, take digital photos, or even be able to play video streaming, power management brought all of these enormous challenges. At the same time, with the acceleration of processor speed, the power management programmes and the various subsystems must keep pace with this change, supporting the provision of support for power. In addition, the new Inspiron 8000 battery technology, especially micro-fuel cell technology business and will soon begin, forcing power chip makers to rethink the future of the power system design.

Accordingly, these new trends for power chip makers have created tremendous business opportunities, encourage them to racking their brains develop more advanced, more and more with their own characteristics and size of a small power management solutions, to support the increasingly complex System power requirements and new features. In order to comprehensive and in-depth understanding  VGP-BPL2 of today's portable applications of the latest trend of power management, the paper invited leading semiconductor company Texas Instruments (TI), flying trillion (Fairchild), Linear Technology (Linear), ON, the semi-(NS), micro-batteries Science and Technology (Microchip) and Li Qi technology to share their insights and wisdom.
