Power Management ICs for OMAP35xx

31.10.2008

Texas Instruments continues to expand its embedded microprocessor power chipset with three new chips that meet the power requirements of the OMAP35xx platform. The TPS65920, TPS65930 and TPS65950 are highly integrated systems that include a variety of peripheral modules in compact packages.

The TPS65950 supports up to 14 power channels. In addition to an integrated 3 MHz DC/DC converter and low noise LDO, it has dual audio codec and driver, control and monitoring system, battery charge controller, LED driver, 3-channel 10-bit ADC, keyboard and vibration driver, high-speed USB transceiver with integrated 5V power supply and PC interface.

The whole system is in a 7x7 mm BGA package. The TPS65920 and TPS65930 have some of the features of the TPS65950, support up to 8 power channels, and come in 10x10mm packages. The new devices add to the ever-growing range of single and multi-channel voltage regulators for OMAP35x processors.

In addition to the TPS659xx family, TI has already shipped millions of TPS3x single-channel 6235 MHz DC/DC converters and TPS65023 multi-channel converters. The TPS659xx, TPS65023, and TPS6235x use a dedicated I2C interface to enable proprietary SmartReflex power and performance management technology.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

IQ is not related to a person's level of intelligence 01.11.2016

The American scientist James Flynn conducted an interesting study, during which he came to the conclusion that over 50 years the general level of intelligence in people has increased, but the level of human consciousness has not improved.

Together with colleagues from the University of Otago in New Zealand, psychology professor James Flynn organized a study whose results disprove the theory that IQ is directly related to intelligence.

Experts argue that intelligence abilities do not actually correlate with IQ indicators, and a person’s mental achievements depend on a number of other factors, including family, and not just genetic predisposition, as previously thought.

Flynn said that on a daily basis he observes smart students who have high potential and are easily managed with modern technologies. However, they are completely indifferent to the history of the world. The scientist is convinced that once outside the walls of the university, they will not differ from the medieval peasants, locked in their cramped "world".

Moreover, the psychologist noted that the worldview of the modern generation is too superficial. Despite the fact that with the development of high technologies, people have developed abstract thinking, and, in turn, the coefficient of intelligence has increased, people still have not learned how to use the potential of their abilities, which allows a number of structures, including political ones, to manipulate their consciousness .
