TI Launches Power Buck Converter to Improve Light-Load Efficiency in Factory Automation and Automotive
Published2016.05.04 09:59TI Korea (CEO Kent Tran) announced the release of two 65V, 150mA synchronous DC/DC buck converters with the industry's lowest quiescent current (IQ) of 10.5uA.
These new products are suitable for factory automation and automotive sensor applications requiring high efficiency. The industrial LM5165 and automotive LM5165-Q1 micro power step-down regulators provide a wide input voltage (VIN) range and dual control modes, maximizing efficiency and saving PCB area. The company also stated that engineers using these regulators can reduce development time for factory and process automation designs by utilizing TI's WEBENCH® Power Design tool.
The LM5165 and LM5165-Q1 micro power regulators operate over a wide voltage range of 3V to 65V, allowing them to handle high transient response in industrial sensor and PLC (programmable logic controller) applications, as well as start-stop and load dump conditions when using 12V/24V lead-acid batteries and the emerging 48V lithium-ion automotive batteries.
In addition, integrating dual MOSFETs reduces PCB area, and the ability to set current limits allows for a reduction in inductor size. Furthermore, since both regulators can operate at high junction temperatures of up to 150°C, they are suitable for use in high-temperature environments. LM5165-Q1 is an AEC-Q100 certified product for automotive applications.
In addition to the LM5165 and LM5165-Q1 products, TI offers a wide range of input voltage DC/DC step-down regulator products, including the LM5017, LM5160, and TPS54062.

Will TI accelerate its automotive business by combining ADAS and infotainment?
Texas Instruments (TI) has selected the automotive sector as a strategic business focus for the future. The company typically introduces itself as "a semiconductor design and manufacturing company leading the development of analog ICs and embedded processors," and this indicates its intention to concentrate its accumulated capabilities in the automotive field. In the ADAS and infotainment sectors, TI's representative solutions are the TDA series and Jacinto processors. Director Kang stated that the Informational ADAS concept is "a functional integrated technology beyond marketing terminology, and to put it simply, you can think of it as the integration of TDA and Jacinto solutions." The TDA SoC is a new product in TI's scalable, highly integrated automotive processor product family, and is a scalable device family designed to meet the requirements of advanced ADAS. The TDAxx product family implements a wide range of ADAS applications in modern vehicles by integrating performance, low power consumption, and ADAS image analysis processing in an optimal combination, thereby enabling enhanced autonomous driving and collision-free driving experience more readily.
