3G Mobile Phone Battery information

3G era will be fully elaborate nikon en-el4a. Dah Sing Energy Co., Ltd. Shandong, with Ren Xiaoping, general manager, said, 3G mobile multimedia, multi-functional mobile phones are bringing high energy consumption, the solution necessary to raise the chip integration and lower power consumption; second is to improve the energy density of batteries. The battery energy density is higher than that of at least 450mAh, can meet the functional requirements of 3G mobile phones. He said the development of lithium batteries since its density is no longer much room for further improve the current energy density available in the market for 420mAh, while the Shandong Tongda batteries through the digital camera battery positive electrode was modified to improve density, the current can be achieved 475mAh, 475mAh is equivalent to 063,048 of 1200mAh, by the end of the 3G push to reach 520mAh Li-ion battery output reached 10 million in the second half. In addition, its advantage is also reflected in the high security, circulation rate. With the big goal is to first open the domestic second and third line of mobile phone brand market, and then enter the domestic market front-line mobile phone brands.

At present more than 100 lithium battery manufacturers, with an average olympus li-10b battery energy density of 850mAh, while the same energy density of up to a large battery 950mAh, the maximum can be 1200mAh. Shenzhen BAK (BAK) Battery Co., Ltd. exhibition personnel, BAK’s 3G cell using new materials, new technology, the highest energy density has reached 1270mAh.

Solar energy use is growing, while mobile phone battery market potential for solar energy applications immeasurable. The exhibition, shows the solar cell to achieve an unlimited mobile phone that can be achieved under low-light charge, the battery capacity of up to 700mAh.

Stereo Audio Power Amplifier good results with olympus li-12b

In the LED backlight driver IC, audio IC field, domestic new army began to make moves. Chiphomer Microelectronics (Shanghai) Co., Ltd., general manager of Lü Chang introduced the company has developed many new products, such as the development of LED backlight driver series IC, its advantage lies in using parallel methods, packages unique light consistency good. New CP2130 for Wu Lu parallel white LED white drivers, the need for series inductance on the radio there is interference, and thus used in parallel. Product conduction voltage drop and generally inconsistent Chiphomer using its patented control technology, brightness up to 0.5%, while generally only 0.3%. Kai Pan is also a live demonstration of the newly developed stereo audio power amplifier CP2260, CP2268, using fully differential technology to realize high sound, will be able to meet domestic market demand. He also said that the current bullish class AB applications market, D amplifier power consumption advantages, inter alia, unless there is a revolutionary breakthrough in the market will not be much improvement. In the touch-screen control system samsung sb-lsm160 for IC and low noise LDO system IC field, Kai Pan is also frequent new product.
