Linear Technology 36V Monolithic 1A Push-Pull DC/DC Transformer Driver with Programmable Duty Cycle Control
The LT3999 operates over an input voltage range of 2.7V to 36V, is targeted for power levels up to 15W and can produce a wide range of output voltages. This makes it well suited for automotive and other applications.
The programmable duty cycle and turns ratio of the transformer sets the output voltage. Several off-the-shelf transformers shown in the data sheet simplify the design.
Amphenol Corporation (NYSE:APH) has entered into a definitive agreement to acquire the Casco Automotive Group (CASCO), a division of Cap-Con Automotive Technologies Ltd. (Cap-Con) for approximately $450 million.
Cap-Con is owned by a private investment fund managed by The Jordan Company II, L.P. and Cap-Con management. The sale is subject to certain regulatory approvals and other customary closing conditions and is expected to close prior to year end.
Casco, headquartered in Bridgeport, Connecticut, is a supplier of highly engineered data connectivity, power, charging and sensor products to the worldwide automotive market, with annual sales of approximately $220 million. Casco has facilities in the Americas, Europe and Asia and employs approximately 1,300 people worldwide.
Intertek has expanded its Antwerp, Belgium, laboratory with engine coolants quality testing capabilities. The ISO 17025 certified Antwerp laboratory has added a full range of engine coolants tests, in accordance to international standards. The new engine coolants lab supports local and regional customers.
“Testing engine coolant quality supports the automotive industry, and better protects engine and cooling systems from severe damage,” said Eric Ris, Country Manager for Intertek Benelux. “Deterioration or degradation of coolant quality can have a negative impact on the performance, safety and reliability of the engine and cooling systems. Engine Coolant Quality Monitoring programs can reduce maintenance and associated costs, increase component life, and increase operational availability and safety for automotive fleets and individuals.”
Coilcraft’s XPL2010 Series of ultra-small, magnetically shielded power inductors are said to combine excellent current handling,low DC resistance and inductance values up to 220 µH in a package that measures just 1.9 X 2.0 mm.
S-1910x Series improves reliability in voltage monitoring and CPU reset functions
Seiko Instruments Inc. announced the S-1910x series voltage detector with SENSE pin for automotive use that enhances reliability in voltage monitoring and CPU reset functions for safer system operation.
Acquisition expands ON Semiconductor’s image-sensor business
ON Semiconductor signed a definitive agreement to acquire Aptina Imaging, a leading provider of high-performance CMOS image sensors for automotive and industrial markets, which are key areas of strategic focus for ON Semiconductor.
Linear Technology announces the LTC3637, a 76V input-capable high efficiency buck converter that delivers up to 1A of continuous output current.
It operates from an input voltage range of 4V to 76V, making it suitable for automotive and other applications.
The LTC3637 utilizes a programmable peak current-mode design to optimize efficiency over a broad range of output currents. It delivers efficiencies as high as 90% and requires only 12µA of quiescent current, maximizing battery run time.
A user-programmable output current limit can set output current from 100mA to 1A as required by the application.

This article describes what start-stop is and the prerequisites for an automotive start-stop system, including its implementation and benefits.
The fuel savings and CO2 reductions are in the five to 10 percent range. With fuel prices rising, taxes increasing for high carbon-oxide emissions, and governmental requirements for vehicles with lower and lower emissions, various measures are needed to increase efficiency and lower emissions.
Texas Instruments (TI) unveiled the industry’s first inductance-to-digital converter (LDC), a new data converter category that uses coils and springs as inductive sensors to deliver higher resolution, increased reliability, and greater flexibility than existing sensing solutions at a lower system cost.
The industry’s first LDC device, LDC1000, is available to order today in a 16-pin, 4-mm by 5-mm SON package for US$2.95 in 1,000-unit quantities.
An automotive-qualified version will be available in the first half of 2014.

Single-pair Ethernet is currently being deployed in automobiles over unshielded twisted pair (UTP) cable. Ethernet shows great promise as an in-vehicle networking technology for the connected car due to its ubiquity, tools, modularity, and IP support.
Although some infotainment display and camera-based advanced driver assistance system (ADAS) applications have introduced Ethernet to prove the technology, serializer/deserializer (SerDes) architectures (sometimes incorrectly called LVDS) typically are simpler, offer higher video quality, and are less expensive in these systems.
Let’s compare these two technologies in detail using a four-camera surround view application as an example.
