ADI power products help customers transition to industry 4

Technical advantages of ADI power supply products

In the industrial 4.0 era, the shape, size, efficiency and EMI performance of power supply are very important in the equipment with a large amount of data and various sensors. ADI sets very strict evaluation requirements for EMI, size and efficiency of products in order to develop more efficient, lower EMI and smaller size power products. Since ADI completed its acquisition of Linear Linglitter in 2017, ADI has combined Linear's high-quality power supply products with its own original power management products to become a series of "Power by Linear" products, which strengthens ADI's advantages in the field of power supply.

ADI power products help customers transition to industry 4

1) solve the EMI problem. ADI has the switching power supply of Silent Switcher technology, which is a breakthrough and innovation from the perspective of Engineering physics. In the design of the chip, two reverse electrical optimizations are made to generate closed magnetic lines and reduce the interference to the external EMI. At the same time, ADI uses flip-flop instead of traditional gold wire to bind the core, thus reducing the current and minimizing EMI. In addition, ADI also obtains better EMI performance through a series of process optimization, which meets CISPR25 EMI standard.

2) In industrial design, the density and complexity of boards are getting higher and higher, reducing the difficulty of customers in industrial field and board design, helping customers reduce the size of power circuit boards and the complexity of circuit design is also a dimension that ADI attaches great importance to in product development and innovation. ADI integrates past very complex power supply systems into one module, such as highly integrated LTM 4668, with an area of only 6.25 mm X 6.25 mm and a thickness of only 2.1 mm. It can connect different outputs in parallel, get different current combinations, help customers save materials, and improve product design flexibility.

3) Improve efficiency and save energy and reduce consumption: from a circuit, there are two aspects of loss must be faced. One is the switching loss of the MOS tube and the other is the loss of inductance as the energy storage device. The loss of these two parts makes it impossible for you to overcome the disadvantages of traditional power supply, and the efficiency is very hard to reach 93% or 94%. However, the efficiency of LT8610AB is excellent, reaching 94% when the load current is 1A, and the efficiency of LT8610AB remains above 92% in the wide range of 1mA to 3A.

According to Zheng Shuda, vice director of product marketing department of Excelpoint World Health Company, ADI Asia-Pacific strategic partner of distribution channels, ADI has launched many products for the automotive, communications and energy markets to help customers move towards the industrial 4.0 era.

1) With the emergence of unmanned driving technology, unmanned factory and driving assistant system, lidar, common radar and related measurement and control unit, as the very core and key platform of future automatic driving and unmanned aerial vehicle, are closely related to people's safety. ADI has introduced several of the lowest noise sources in the world, LT3042 and LT3045, which can be used to meet the needs of precision, performance and stability for radar, radio frequency and high frequency applications. Noise is only 0.8 microvolts, similar to batteries, providing better performance and reliability for the field of automatic driving and promoting the development of the industry. ADI's new Silent Switcher technology can also be used in driverless and intelligent factories. In addition, ADI has launched and dominated the new concept of PoDL (Power Over Data Line). In the future, the use of Ethernet connection in automobiles can save a lot of cable construction and weight, improve reliability and reduce the difficulty of construction.

2) Faced with the 5G communication market, ADI has developed a converter without inductance, which uses four MOS transistors to do voltage conversion. Its area is only 2.8 X 2.8 cm, and it can output 48 volts to 24 volts 500 W. It can achieve 99% efficiency in the whole range, and can achieve more than 97% efficiency in the past 12 volts, which is beyond the traditional power supply. The new generation LTC7821 hybrid converter integrates a capacitor-based energy transfer circuit with a standard voltage-lowering circuit and turns it into a hybrid circuit with a efficiency of 97%.

3) smart grid, ADI also has a complete solution. ADI has specialized devices with MPPT, which can achieve maximum solar energy in the same light.

As the basic composition of electronic circuit, power supply can be said to be everywhere, communications, automobiles, consumer electronics... In today's era, power supply is widely used in various popular market applications, and becomes an indispensable part of it.
