Diodes Incorporated Closes Acquisition of BCD Semiconductor Manufacturing Limited
Diodes Incorporated today announced that it has completed its acquisition of BCD Semiconductor Manufacturing Limited (BCD) in an all cash deal, valued at approximately $151 million. Under the terms previously announced, each ordinary share, par value $0.001 per share, of BCD (the “Shares”), including Shares represented by American Depository Shares (“ADSs”), has been converted into the right to receive cash.
Fast And Efficient 650V XPT Trench IGBTs Announced By IXYS
IXYS have today introduced a new IGBT product line – 650V XPT Trench IGBTs. The current ratings of devices in the new product family range from 30A to 200A at a high temperature of 110C. With on-stage voltages as low as 1.7V, these new XPT devices are designed to minimize conduction and switching losses, especially in hard-switching applications.
Sound Quality Breakthrough With 9.5V Boost Voltage In Mobile Micro Speakers
In a push for better sound quality and more output volume, leading mobile phone makers have been raising the internal voltage used to drive micro speakers – from 3.3V through to 5V, and recently as high as 8V. NXP is launching its new TFA9890 speaker driver IC, which enables an unprecedented 9.5V boost voltage from an integrated DC-DC converter. Increasing the voltage headroom in the audio driver IC prevents amplifier clipping and keeps sound q...
Variable-Wavelength Modules For Optical Test System
Yokogawa has extended the range of plug-in modules for use with its AQ2200 Series multi-application optical test system by introducing two new tunable light source modules that allow the test wavelength to be varied to suit the user’s application.
Breakthrough Sound Quality On Mobile Devices
In a push for better sound quality and more output volume, leading mobile phone makers have been raising the internal voltage used to drive micro speakers -- from 3.3V through to 5V, and recently as high as 8V. This week at Mobile World Congress 2013 (Hall 7, Stand A111), NXP Semiconductors is launching its new TFA9890 speaker driver IC, which enables an unprecedented 9.5V boost voltage from an integrated DC-DC converter.
World’s Most Highly Integrated SoC for TV SoundBar Audio Applications
The seemingly insatiable demand for ever-thinner profiles is compromising the audio quality output of even top-end flat panel TVs, thereby creating enormous market opportunities for digital sound projectors (SoundBars) capable of delivering an audio fidelity that matches today’s high-definition video reproduction.
Osram Coordinating Project For Developing High-Brilliance Infrared Laser Sources
In order to help improve the performance of laser systems while reducing production costs, Osram Opto Semiconductors is coordinating the IMOTHEB project (Integrated microoptical and microthermal elements for diode lasers of high brilliance) as part of the “Integrated Microphotonics” initiative. The project partners are DILAS Diode Laser and the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), a nonprofit research or...
