Synchronous DC-DC Regulators Texas Instruments LM76002/3

18.04.2018

Texas Instruments has released new buck converters with up to 60 V input and up to 2.5 A output for the LM76002 and up to 3.5 A for the LM76003.

With a wide input voltage range, it is possible to simplify input protection circuits for 24V applications in industrial and automotive systems. Switching frequency adjustable over a wide range (350...2200 kHz) allows you to optimize the device either in terms of power loss or in terms of the space occupied by the solution on the board. The ICs have a large pad on the bottom of the package, which is designed to absorb power losses, which ensures excellent thermal behavior.

The presence of special grooves inside the pins of the microcircuit improves the quality of the solder joint and provides 100% visual control of the assembly process.

Technical specifications:

input voltage range: 3,5...60 V (maximum 65 V);
output voltage from 1,0 V to 95% of Vin;
rated output current: up to 2,5 A (LM76002) and up to 3,5 A (LM76003);
frequency is adjusted in the range: 350...2200 kHz;
low self-consumption current: 15 μA;
maximum efficiency reaches 97%;
configurable soft start (6,3ms by default);

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, ... >>

34" IPS monitor LG 34UM95 with a resolution of 3440 x 1440 pixels 17.03.2014

LG has started selling the UM95, UM65 and UB65 series monitors in Europe, announced in mid-December last year. Each line includes only ultra-wide monitors based on IPS matrices with an aspect ratio of 21:9.

The flagship model LG 34UM95 is offered in Europe at a price of 999 euros. This monitor is equipped with a 34-inch LCD panel with 3440 x 1440 dots resolution, 320 cd/m1000 brightness, 1:5 contrast ratio, 34ms pixel response time. LG 95UM14 is endowed with a three-port USB hub, two speakers with a total power of 1.2 W, as well as DisplayPort 2 and Thunderbolt 1.4 video inputs and two HDMI XNUMX.

The UM65 series monitors are cheaper. Their cost is as follows: LG 25UM65 (diagonal - 25 inches) - 279 euros, 29UM65 (29 inches) - 449 euros, 34UM65 (34 inches) - 609 euros. The characteristics of their matrices are as follows: resolution - 2560 x 1080 pixels, brightness - 300 cd / sq.m (in LG 25UM65 - 250cd / sq.m), contrast - 1000:1, response time - 5 ms. Each of the three models is equipped with two speakers, two HDMI ports and one DVI.

Simultaneously with the models of the UM65 series, the 29UB65 model went on sale, which differs from the 29UM65 only in the presence of a transformable stand with the ability to rotate the display at an angle of 90 ° (pivot). Price LG 29UB65 - 489 euros.
