When talking about the industrial application field that accounts for more than 40% of ADI's high-power DC power supply business, Liang Zaixin (Lorry), marketing director of ADI's high-power DC power supply products in my country, concluded at the beginning, "The true essence and foundation of Industry 4.0, considering more It’s more about how to provide real-time control, software-manufacturable I/O, and the reliability, safety and healthy operation of all these devices.”

To achieve higher productivity, Industry 4.0 applications need to meet innovation needs in flexibility, power, communication, safety, reliability and other aspects. The use of all industrial products is inseparable from high-power DC power supply. In the three dimensions of high efficiency, small size, and low EMI (electromagnetic interference), ADI can provide strong support and a series of innovative products to meet the safety and reliability requirements of high-power DC power supplies in different industrial application fields.

In the industrial field, EMI is an unavoidable problem. Especially now that factories are introducing large-scale robot operations, it is easier for the system to crash due to EMI problems, causing huge losses.

Regarding the ultra-low EMI of high-power DC power supplies that is difficult to achieve, Lorry gave an example of the latest generation LT8614 chip using Silent Switcher technology. It has made breakthroughs and innovations from the perspective of engineering physics. It not only passes through two reverse current loops Optimize the magnetic field closure path, and at the same time control the ringing on the rising edge of SW through system loop optimization to be very small. Coupled with its highly optimized packaging process, gold wires are no longer used to bind the core, but guide assembly is used. Reduced current board, its EMI is quite low. In addition, it also greatly reduces ripple, solves the noise problem, and improves the reliability and stability of the system.

In my country's robotics, industrial control fields, and even the automotive field, most customers are very interested in Silent Switcher technology, because in the past, almost all industrial customers or automotive customers had to go through half a year just to solve the EMI certification problem. Take the time to make rectifications, and only after passing them can you go public. The emergence of Silent Switcher technology can save more than half a year.

In order to solve the problem of large voltage fluctuations in special industrial applications, ADI has also launched a very wide-voltage isolated high-power DC power supply (as shown in the picture above, its high-power DC power supply ranges from 20V to 540V). At the same time, in order to reduce the design space for industrial customers and board cards, ADI also designed a highly integrated high-power DC power module. This can save customers costs in equipment procurement, production reliability and materials. For example, the highly integrated LTM4668 measures only 6.25mm × 6.25mm × 2.1mm (length × width × height).
