DualCool™ NexFET™ power MOSFETs with innovative package offer up to 80 percent higher power dissipation and up to 50 percent more current in a standard footprint

PRNewswire

DALLAS

(NYSE:TXN)

DALLAS, Jan. 11 /PRNewswire/ -- Texas Instruments Incorporated (TI) today introduced the industry's first family of standard-footprint power MOSFETs that dissipate heat through the top of the package for high-current DC/DC applications. DualCool™ NexFET™ power MOSFETs reduce end equipment size, while providing up to 50 percent more current through the MOSFET and improving thermal management over other standard-footprint packages. See: www.ti.com/dualcool-pr. This new family of five NexFET devices allows computing and telecom system designers to use higher current processors with expanded memory while saving board space. These MOSFETs in an advanced package can be used in a wide range of end applications including desktop personal computers, servers, telecommunications or networking equipment, basestations, and high current industrial systems. "Our customers demand higher current DC/DC power supplies in a smaller footprint to meet the need for increased processing power in the broad infrastructure market," said Steve Anderson, TI's senior vice president and worldwide manager, Power Management. "DualCool NexFET power MOSFETs meet this need by conducting more current in the same form factor." Key features and benefits of DualCool NexFET power MOSFETs:

• Single phase 35-A synchronous buck converter MOSFETs, using single MOSFETs for both the high and low side switches in high-current DC/DC applications.
• Enhanced packaging technology reduces thermal impedance to top of package from 10 degrees to 15 degrees C per watt to 1.2 degrees C per watt, increasing power dissipation capability by up to 80 percent.
• Efficient dual-side heat sinking enables up to 50 percent more current through the FET, giving designers the flexibility to use higher current processors without increasing end equipment size.
• Industry-standard SON package with a 5-mm x 6-mm footprint eases design and keeps cost down, saving 30 mm2 compared to using two standard packages.

Availability and pricing DualCool NexFET devices are available in volume now from TI and its authorized distributors. Suggested resale pricing for the CSD16325Q5C is $1.47 in 1,000-unit quantities. Samples and application notes are available. Find out more about TI NexFET MOSFETs and other power offerings by visiting the links below:

Swimovate's Pool-Mate is fully automatic lap and stroke counter that calculates speed, distance, calories and efficiency

PRNewswire

DALLAS

(NYSE:TXN)

DALLAS, Dec. 14 /PRNewswire/ -- Innovating advanced swim training aids for the fitness industry, Swimovate Ltd leveraged Texas Instruments Incorporated's (TI) (NYSE: TXN) ultra-low power MSP430™ microcontroller (MCU) to drive its cutting-edge Pool-Mate sports watch, the first fully automatic lap and stroke counter on the market. Based on a single MSP430 MCU, Swimovate's intelligent Pool-Mate allows swimmers to automatically count strokes and laps as well as calculate speed, distance, calories and efficiency.

"As amateur tri-athletes, we noticed there were several speed and distance computers for runners and cyclists, but only extremely basic swimming aids, ill-equipped to execute the advanced functionality necessary for training," said Lisa Irlam of Swimovate. "TI's MSP430 MCU offered the processor performance, ultra-low power consumption and direct LCD drive we wanted for the Pool-Mate to effectively and automatically calculate strokes, laps and efficiency, leaving swimmers free to concentrate on their technique."

The Pool-Mate is a comprehensive signal processing watch powered from a 3V lithium coin cell battery without voltage regulators, and includes an accelerometer and features that enable athletes to time running, cycling and even triathlons. The watch records total session statistics, or individual sets and timing rest periods so the swimmer can see how his or her stroke changes through their workout. All the data is available for immediate recall and is stored in the large log for comparison. With an accuracy rate of more than 99.7 percent, the Pool-Mate is easy to set-up, requires no calibration and will work with all the major strokes and swimming abilities, from professional to recreational swimmers.

"The Pool-Mate provides swimmers with a sleek, easy-to-use aid that eliminates traditional training challenges," said Adrian Valenzuela, product marketing manager for MSP430 MCUs. "TI prides itself on enabling customers to solve everyday obstacles, and Swimovate's breakthrough swim aid demonstrates how we've been able to do that with the right balance of ultra-low power consumption, performance and peripherals in TI's MSP430 MCUs.

TI and Swimovate are committed to delivering solutions that meet customer needs and provide a unique consumer experience.
