Diodes Incorporated introduced its ZXGD3102 active OR’ing controller chip that enables shared power system designers to replace heat-dissipating blocking diodes with high-efficiency MOSFETs. This is said to ensure cooler running, lower maintenance and higher reliability in up-time-critical telecom, server and mainframe applications. The ZXGD3102 is specifically
Taiyo Yuden's LS6Q-1612A-RH — low-profile DC-to-AC inverter is intended for driving cold-cathode fluorescent lamps (CCFL) in Liquid Crystal Display (LCD) back-lighting applications. Designed specifically for use with 12-17” industrial-grade LCD panels, the LS6Q-1612A-RH provides dual LCD panel capability. It features
The California Energy Commission (CEC) is moving ahead with a proposal that could make Plasma TVs legally obsolete. Based on the 2008 Report, “Draft Efficiency Standards for Television” (which drew heavily from Pacific Gas and Electric Company findings), the proposal would set a cap on the maximum active mode power usage (watts). This would effectively ban the sale of Plasma, DLP, rear projector, and certain LCD TV’s in California
National Semiconductor has extended its family of low-power Boomer Class D audio subsystems with two devices that are said to simplify portable product design. The LM49352 mixed-signal audio subsystem and LM49151 analog subsystem are targeted at smart phones, full-featured phones, portable gaming devices and portable GPS devices. The LM49352 integrates
Microchip Technology announced the first seven next-generation 16-bit dsPIC Digital Signal Controllers (DSCs) for common, multi-loop Switch-Mode Power Supplies (SMPSs) and other power-conversion applications. The new dsPIC33F “GS” series digital-power DSCs enable digital control loops with four to eight high-speed, 1 ns resolution pulse-width-modulators (PWMs) and one or two 10-bit, on-chip ADCs, providing
Murata Power Solutions has introduced a series of digital AC ammeters with alarm for the measurement and display of complex, true-rms, non-sinusoidal AC currents. The DATEL ACA-20RM-ALM AC Ammeters are completely self-contained and include a built-in current transformer. The integral alarm is triggered when the user-settable over current value is exceeded. The red LED display
Douglas Electrical Components' (DECo) Portplate systems, which combine fully assembled, pre-tested multiple feedthroughs on a single plate are said to minimize the amount of potential downtime due to system leaks, which would usually result in high costs and delays, associated with troubleshooting. These plates can

Tesla Motors' Model S is a stunningly beautiful car that that builds upon the cachet of the Roadster and proves the company is serious about pushing electric vehicles into the mainstream. Company CEO Elon Musk compared the luxury and practicality of his car to the BMW 5 series and Mercedes Benz CLS sedans and said history will place it alongside the Ford Model T.
Purportedly resistant to impact, thermal shock, vibration, and fatigue cracking, the Supreme 10HT adhesive from Master Bond is serviceable over a temperature range of 4 K to over 400°F. It is resistant to chemicals including water, oil, fuels, and most organic solvents. The adhesive meets NASA low outgassing specifications
