4Q 2007 MediaTek mobile phone chip market share in China dropped to 5 percent

MediaTek the fourth quarter of 2007, shipments of mobile phone baseband chip by the power amplifier (PA) out of stock issues affecting the fourth quarter, shipments of less than originally expected quarterly growth rate of 9%, between about 5-7% , MediaTek lowered 2 degrees and therefore revenue, a decrease of 25%. It is understood that positive trapped in the power amplifier MediaTek shortage problems, the Chinese government strongly support the mobile phone chip maker Spreadtrum Communications (Spreadtrum) baseband chip shipments in the fourth quarter was a record high, fourth quarter revenue growth rate is estimated to be 22%. Estimate the fourth quarter of mobile phones in China Spreadtrum baseband chip market share can grow up to 2 percent, while MediaTek market share could fall into the following 5. It is understood that in 2008, M...

4V to 60V Linear Technology introduced the DC / DC Controller LT3844

(Electronic markets Reuters) Linear Technology Corporation (Linear Technology Corporation) introduced the input range of 4V to 60V, DC / DC Controller LT3844, 100kHz to 500kHz with the devices adjustable switching frequency, allowing optimization of the power of the size and efficiency. The higher the switching frequency, the user can use smaller inductors and capacitors, and in the lower frequencies, the user can optimize efficiency. For noise-sensitive applications, LT3844 can be synchronized to a 100kHz to 600kHz external clock. As a general controller, LT3844 can be used in several DC / DC topologies, such as buck, boost, negative output, and SEPIC (buck - boost). In addition, the output voltage is 1.23V to 36V can also be a wide range of adjustment. Applications include high voltage power supply system of automotive and heavy equipme...

4x400mA LED driver austriamicrosystems

Austriamicrosystems (austriamicrosystems) for the rapid development of high brightness and high brightness LED applications market launched a 4 × 400mA LED driver AS3691, which has expanded its LED driver product line. "High-brightness LED applications with the rapid development of LED driver IC can only provide general general brightness or the backlight LCD display is no longer the best solution." Austriamicrosystems Business Unit Senior Vice President of Communications Alexander Harrer and general manager, said, "AS3691 is ideal for high-brightness white and color LED applications, because it not only supports very high currents, but also to ensure accuracy in the case of providing great flexibility, improve efficiency, and convenient easy to use. " AS3691 has four independent high precision current source, the absorption of each cur...
