Enhanced LED Driver IC

09.05.2020

Maxim Integrated Products has released a new family of ICs for automotive circuits. The MAX25601A/B/C/D contain a synchronous boost controller followed by a synchronous LED buck driver controller.

The boost controller's input voltage range of 4,5V to 40V is ideal for automotive applications. In fact, this controller serves as a preliminary boost regulator for the second stage of the microcircuit - a step-down LED controller.

The synchronous boost converter operates in inductor current control mode and can be connected in parallel with another device to increase output power. The SYNCOUT pin, designed to control the RT / SYNCIN pin of another device, allows you to organize anti-phase synchronization of two microcircuits operating in parallel. The switching frequency of the boost converter is programmable from 200 kHz to 2,2 MHz. To reduce the level of electromagnetic interference, an expansion of the spectrum of the synchronization signal is implemented.

An internal digitally controlled soft-start circuit ensures that the buck output ramps up smoothly. The list of safety features includes pulsing mode, overvoltage protection, and crystal overtemperature shutdown.

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, ... >>

Samsung 1TB SSD 16.12.2013

Samsung has introduced the first 1TB mSATA SSD in the market for laptops.

The drive consists of four multi-layer modules, each of which contains 16 16 GB flash memory chips based on 10-nm technology.

The device is equipped with a proprietary Samsung controller and Samsung TurboWrite technology, which provide 98K IOPS in random read mode and 90K IOPS in random write mode. Sequential read speed is 540MB/s, write speed is 520MB/s.

The drive is about 4 times smaller, 2,5 times thinner and 12 times lighter than a 2,5-inch hard drive. Its thickness is 3,85 mm and its weight is 8,5 g.

The new drive is part of the new 840 EVO mSATA SSD lineup. In addition to the 1TB model, it includes 120GB, 250GB, and 500GB models. All of them demonstrate the same speeds as the older model.

It is planned to start selling new drives on the global market before the end of December.
