Linear Technology 38V Synchronous Step-Down Controller with 24V Output Capability Draws Only 50µA in Standby
August 21, 2014 by John Day
Linear Technology Corporation introduces the LTC3807, a low quiescent current synchronous step-down DC/DC controller that draws only 50µA in standby mode with the output voltage in regulation.
The 4V to 38V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sources and battery chemistries.
The output voltage can be set from 0.8V to 24V at output currents up to 25 amps with efficiencies as high as 95%, making it well suited for automotive, heavy equipment, industrial and robotic applications.
Infineon Technologies and International Rectifier Corporation have signed a definitive agreement under which Infineon will acquire International Rectifier for $40 per share in an all-cash transaction valued at approximately $3 billion.
The acquisition combines two semiconductor companies with leadership positions in power management technology. By the integration of International Rectifier, Infineon complements its offerings and will be able to provide customers with an even broader range of innovative products and services. Infineon will also benefit significantly from greater economies of scale as well as a larger regional footprint.
ITS America Statement on U.S. DOT Advance Notice of Proposed Rulemaking on V2V Communication Technology
Intelligent Transportation Society of America (ITS America) President and CEO Scott Belcher made the following statement in response to the National Highway Traffic Safety Administration (NHTSA) release of an advance notice of proposed rulemaking (ANPRM) and supporting comprehensive research report on vehicle-to-vehicle (V2V) communication technology.
“We applaud the U.S. Department of Transportation for taking this significant step to dramatically reduce the number of lives lost in traffic and pedestrian crashes. Today’s report and advanced rulemaking announcement reinforces the real-world safety benefits reported by our members in the automotive and tech communities, that vehicle-to-vehicle communications technology represents the next giant leap in automotive and pedestrian safety.
NNG, Budapest-based developer of iGO Navigation software, acquired nfuzion, an American HMI prototyping company. The acquisition will allow NNG to broaden its presence in automotive on-board systems, including infotainment and HMI (human-machine interface).
nfuzion capabilities range from industrial and UI design to mechanical and electrical engineering. They bring 14 years of in-car entertainment knowledge to NNG, having worked with numerous international car brands, and give NNG a new range of tools, products, and consulting to utilize on future projects. NNG and nfuzion had previously worked together and expressed mutual interest in combining their efforts.
Continental is putting together an international team of innovators from the IT and automotive industries who will focus on Intelligent Transportation Systems (ITS).
The new business unit, called “Continental Intelligent Transportation Systems, LLC”, will be headquartered in Silicon Valley and headed by Seval Oz, an expert in vehicle networking and automation. In her previous role she worked on Google’s self-driving car project.
“This step is an excellent example of our strategy to make the car an integral part of the ‘Internet of Everything’. Our key objectives include eliminating road accidents, minimizing energy consumption, maximizing comfort and usability of vehicles, and enabling them to exchange information with each other in real-time,” said Dr. Elmar Degenhart, Continental CEO.
Sensata Technologies Holding N.V. (NYSE: ST) announced that its wholly owned indirect subsidiary Sensata Technologies B.V. has reached agreement to acquire the Schrader group of companies from Madison Dearborn Partners, LLC for a total enterprise value of $1.0 billion. Schrader is the global leader in tire pressure monitoring sensors (TPMS).
The transaction provides TPMS and additional low pressure sensing capabilities that address large and fast growing sensing markets. The transaction is subject to regulatory approval and is expected to close during the fourth quarter of 2014.
Elektrobit (EB) plans to build a new automotive software development facility in Oulu, Finland. The new site will have up to 40 software engineers by the end of 2014 focusing on the development of embedded automotive software.
EB’s automotive business group has grown steadily over the past few years and currently employs more than 1,100 people in Germany, France, Austria, Romania, the USA, China and Japan. Expanding its operations in Oulu, Finland will offer the company an opportunity to further grow its software engineering capacity for current and future needs. The site will be located in Teknologiakylä Oulu, where EB’s wireless business group operates.
Linear Technology Corporation announces the LT3062, a high voltage, low noise, low dropout voltage linear regulator. The IC delivers up to 200mA continuous output current with a 300mV dropout voltage at full load.
The LT3062 features a wide input voltage range of 1.6V to 45V, delivering adjustable output voltages from 0.6V to 40V.
A single capacitor provides both programmable ultralow noise operation – only 30µVRMS across a 10Hz to 100kHz bandwidth – and reference soft-start functionality, preventing output voltage overshoot at turn-on.
The project, funded by DTE Energy, will provide employees with 360 covered parking spaces and 30 charging stations for plug-in electric vehicles such as the company’s Ford Fusion Energi and C-MAX Hybrid Energi. A kiosk will also be on site offering general information to visitors about solar power and specific details about the Ford carport.
Volvo Trucks’ model year 2016 VN series highway tractors will deliver even greater fuel savings compared with previous generation models through an assortment of aerodynamic and powertrain enhancements.
Further sculpting of airflow around the exterior and underneath the hood improves fuel efficiency by up to 3.5 percent. Volvo’s new XE-Adaptive Gearing and Torque Management options can provide fuel efficiency improvements of more than 2.5 percent.
