AD1803JRU-REEL_AD232JN Introduction

With the maturity and progress of the process technology and the increase in market demand, more and more companies use advanced processes below 20nm to design and produce ICs and devices, which makes more and more IDMs and foundries eliminate low-efficiency production. fab. .

Texas Instruments (TI) today introduced an ultra-low power switching regulator TPS62840, its operating quiescent current (IQ) can reach 60nA, only 1/3 of similar devices in the industry. It delivers very high light-load efficiency of 80% at 1-µA loads, enabling designers to extend the battery life of their systems or use fewer or smaller batteries to shrink their overall power solution size and reduce costs. In addition, the new DC/DC converters have a wide input voltage (VIN) range of 1.8V to 6.5V to support a variety of chemistries and configurations.

Analog Devices leverages its unique domain application expertise to play an important role in end-use applications and positively impact customers' businesses. ADI's advances in software are deeply influencing how customers choose and use their solutions. .

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

In addition to these features, the C2000 F2838x microcontrollers offer enhanced real-time control performance and greater flexibility than previous generation C2000 series microcontrollers. For more information on the F2838x family of microcontrollers, .

Professor Kerstin Mey, Vice-Chancellor of the University of Limerick, said: "ADI is our firm and strong long-term partner, and I am delighted that ADI is working with us on this exciting new project. We are looking forward to working with ADI to achieve this Important ways to reshape the way future software engineers are trained.”.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

"The new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

The propagation speed of sound waves in solids is ~5000m/s, which means that the acoustic impedance of solids is about 105 times that of air, so 99.995% of the sound wave energy will be reflected back at the boundary between the solid and the air, which is the same as the original wave (incident wave). together to form a standing wave. On the other side of the oscillating structure, the acoustic impedance of the piezoelectric material is not much different from that of other substrates (such as Si), so the piezoelectric layer cannot be deposited directly on the Si substrate. In order to keep the acoustic wave in the piezoelectric film to oscillate, there must be sufficient isolation between the oscillating structure and the external environment to obtain a small loss and a large Q value. .

The BAW filter is more suitable for frequencies above 2.5GHz. The manufacturing process of the BAW filter is also very consistent with the existing IC manufacturing process, and is suitable for overall integration with other active circuits. .

The charger can provide a power density of 155 mW/mm2 (100 W/in2), which is about twice higher than the market. The new buck-boost charger helps engineers reduce solution size and bill of materials (BOM) and is TI's first device to fully integrate the following components: switching metal-oxide-semiconductor field-effect transistor (MOSFET), charge path management FETs, input current and charge current sensing circuits, and dual input select drivers. . The reduction in component count is valuable for applications such as smart speakers; and as market adoption increases, the size and cost of these applications continue to shrink.
