With the development of various electrical products such as wearable products, smart products, and small and medium home appliances, higher requirements have been put forward for power management ICs. For higher application requirements, how will the power management IC technology evolve?

For electronic products, power is an important guarantee for its vitality. Without a power supply, electronic products cannot operate normally. The efficient power management makes the performance of electronic products more prominent, which is the value of the power management chip.

With the development of various electrical products such as wearable products, smart products, and small and medium home appliances, higher requirements have been put forward for power management ICs. For higher application requirements, how will the power management IC technology evolve? In response, the reporter interviewed David Lucchetti, Director of Market Applications, Industrial and Power Conversion Products Division, Greater China and South Asia, STMicroelectronics. David Lucchetti focused on three aspects of sharing: new interface technology, fast charging, intelligent management.

New Interface Technology: USB Type-C Realizes Bidirectional Transmission

The application of the old USB charging is mainly focused on the mobile phone, and because the USB interface is inconsistent, it can hardly be inserted once. In addition, USB protocol interface can only be 5V, 500mA current capability, and power can only be transmitted in one direction. With more and more devices having USB interface requirements, a new standard interface technology emerged, completely overcoming the limitations of traditional USB charging.

David Lucchetti pointed out that USB Type-C has the following characteristics: 1. The maximum data transfer speed reaches 10 Gbit/s, which is also the standard of USB3.1; 2. It supports “positive and negative insertion” functions that can be inserted from both sides; 3 Standard-size cable with Type-C connector can supply up to 100W with 3A current, and also supports "USB PD" beyond the existing USB power supply capability.

USB Type-C port has USB3.1 here and 3.0 two kinds, USB3.1 transmission speed is faster. The power transmission of the new interface technology is bidirectional and can have two transmission power modes. Users can not only use laptops to charge mobile devices, but also use other devices or mobile power to charge laptops. That is: The previously charged device can also be used as a rechargeable device. In addition, USB-TypeC is backward compatible, USB-TypeC can be compatible with the old USB standard, but users need to purchase an additional adapter to complete compatibility.

"There are 5 types of protocols for USB Type-C. The previous ones were about 5V, 2A, 10W, and the most important ones were in handheld devices. There are 5V, 2A or 12V, 1.5A, and they can reach 18W. Power 36W, Pad, Tablet, or other devices can use this type of USB Type-C protocol. For high power, a power range of 60W can already be achieved. For protocol 5, it can reach ranges of 100W, 20V, 5A." David Lucchetti said.

It is understood that in the power management IC, currently STMicroelectronics uses Combo chip, integrated (PFC + LLC) in one of the STCMB1, plus DC-DC, as well as its USB3.0 interface technology.

The industry expects that the devices equipped with the USBType-C technology USB3.03.1 interface will reach 2.1 billion units. After 2016, 12% of mobile terminals will use a Type-C interface like this.

Fast charging scheme: 40% charge for 10 minutes

With more and more electrical equipment, mobile phones and other electrical equipment have a longer standby time, it is very necessary.

For Qualcomm's Quick Charge standard, the initial charge is 10% for 10 minutes. Later, the 2.0 standard is to charge about 30% of the power in 10 minutes. Now, basically, Qualcomm 3.0 charges 40% of the battery power in 10 minutes. The Qualcomm 3.0 protocol can save charging time for fast charging.

Corresponding to the Qualcomm Quick Charge3.0 protocol, David Lucchetti pointed out that STMicroelectronics has launched the STQC 30 fast charging scheme. STQC30 components have few peripheral components, complete functions, small package, integrated bleeder resistance, can set current distribution, low standby power consumption, adaptive overvoltage protection, Vcc voltage range expansion (supports working voltage less than 3V).

Intelligent management: technical solutions and material processes

Intelligent management is another new trend of power management ICs. It is mainly implemented through smart switches. There are two ways to implement the smart switch: one is a technically intelligent technology solution with an intelligent core, and the other is a material and semiconductor process technology that allows product intelligence.

At present, from the small-scale market of data communication/telecom server to the large-scale market of consumer electronics, the power supply presents a digital trend.

For high-power industrial power supplies, it is widely used in data center processors and industrial high-power power supplies. This is the digital power supply Smart Power Supply. In terms of digital power supply, according to David Lucchetti, the current smart power solution has two aspects: First, there is digital nuclear processing, plus the main control components, resulting in integrated solutions. The second is the interactive design GUI interface for design and application, which can shorten the time to design time and design cycle of Time to market and make the program more quickly respond to this market demand.

For small power supplies, consumer electronic solutions are mainly targeted. The solution is that through the semiconductor process, there will be magnetic isolation technology for isolated products; there is also Linear Linear processor and so on, which is also one of the performance of the smart.

Smart power is mainly focused on lighting. It is reported that ST currently owns the STLUX platform. It can be used in LED applications, HID applications, fluorescent lamps, PWM dimming function, and 0-10V or Triac thyristor dimming. can be realised. The smart performance of the STLUX platform is that there is an STM8 core. This digital core allows the design to be more flexible and responsive. If it is a simulation scheme, engineers will need to redo the topology or do some design again. The digital solution, due to the interaction of Graphicu serinter face, engineers do not need to make major changes to the hardware, and only need to do software adjustments to get a good way to practice and quickly complete the new digital design.

In the intelligent performance of lighting, it more meets the needs of the humanities, such as dimming and dimming of lamps, multiple control of lamps, and multi-channel dimming control. At the same time, intelligence is also made more convenient. For example, street lights can be controlled through power carriers. Therefore, this kind of intelligent lighting can be applied not only in civil use but also in commercial and industrial lighting.

Urbanization can be understood as urbanization, which involves major social changes in the transition from small-scale peasant economy to industrial economy, from self-sufficient economy to open economy, and from low technology content to new technologies. The so-called new urbanization is the emphasis on the civilization and rational evolution of concepts and behaviors, rather than the advancement of the past, as opposed to the old urbanization. This has led to the reproduction of low-level reproduction and waste of resources.

The promotion of urbanization will inevitably drive the development of the decorative hardware industry. There will be new growth points in the domestic market. The assembly number for the recovery of the industry is already sounding, and it is just around the corner when it comes to warming up. For the decoration hardware industry, the long-awaited new urbanization plan has finally emerged. The advancement of urbanization is to allow the development of decorative hardware in the next few years.

Nowadays, although the entire decorative hardware industry has not yet shaken off the haze, the country has vigorously promoted the construction of urbanization and released a strong signal bomb. This will inevitably be another good opportunity for the development of the decorative hardware industry. However, the entire industry may not be able to rest assured that it is safe. Sit and wait for urbanization to release tremendous energy. The entire decoration hardware industry must not only see the dawn brought by urbanization, but also must be self-rescue, and the economy is weak. We must calmly deal with the situation at the bottom of the valley. Now that we have gone from head to foot, our mindset has been adjusted and our mentality has been adjusted to be better. Timely situation.

Decoration hardware industry still has a lot of homework to do. It is imperative to reflect on the development status of the industry, how to change the current status, and reproduce the glory of the year. These all require the decoration hardware industry to settle down and scrutinize. Only by knowing oneself can we know one another, and only by learning to use our power to strengthen one's self-confidence, we can learn from the essence of ancient history to enrich ourselves. The decorative hardware industry is inextricably linked with urbanization. It goes without saying that the promotion of urbanization will inevitably drive the development of the entire industry. Enticing big cakes are right in front of us. Can we eat and eat? How much you eat depends on your own ability.

OFweek Smart Home Network News Under the trend of intelligent leading the air-conditioning industrial structure upgrade, the "smart" on the mirror rate is getting higher and higher. Recently, the National Information Center announced the best-selling brand and model list of smart air conditioners in May. According to the data, Haier smart air-conditioner ranks first in both May sales and sales. In the list of best-selling smart air-conditioning models, Haier's "energy-saving wind" self-cleaning air conditioner has become the sales champion.

According to the data released by the National Information Center, domestic smart air conditioners have a strong growth momentum. From January to May of 2017, the domestic smart air conditioner market maintained a high level of concentration. The top three brands accounted for 95% of sales, of which Haier’s smart air conditioners continued to be 41 The first month of sales, the industry leader stable position.

In the intelligent air-conditioning market, smart self-cleaning products have the fastest growth rate. The "White Paper on Intelligent Self-cleaning Industry" just released shows that intelligent self-cleaning air conditioners have become the largest category of smart air conditioners. According to market sales data, Haier's intelligent self-cleaning air-conditioning sales doubled year-on-year from January to May, and in the May smart air-conditioning best-selling models ranking, Haier's “energy-saving wind” smart self-cleaning air-conditioning became the best-selling model, again confirming Intelligent self-cleaning has become the first single product in the smart air conditioner market.

At present, the intelligent self-cleaning air conditioner has developed into the most representative product in the industry, and it gradually becomes popular based on user interaction. Haier, the creator of intelligent self-cleaning air conditioners, has continuously deepened its interaction with users through demonstrations such as “bathing”, “white towel” and “one cup of water” in the national stores, promoting smart self-cleaning that has been widely recognized by the market and users. . In the market terminal, smart self-cleaning air conditioners are standard in Zhangjiajie Country Garden Phoenix Hotel villa group, Urumqi aid Xinjiang cadre apartment, or Lanzhou Qishi Hulu Art Museum. Among them, Phoenix Hotel Villa Group is also the largest self-cleaning air conditioner installed. an item.

According to authoritative sources in OFweek's smart home network industry, smart homes have really entered the second phase, which is based on the intelligence of different single smart products on the first stage of single product intelligence, but these are still far from being able to Let the "smart home" truly landing, but also continue to strive to enter the third phase, that is based on artificial intelligence, big data, etc. to achieve a fully automated, self-learning, self-perceived smart home system. In the third stage of smart home, the cloud platform provides support.

Smart homes are usually defined as residential buildings. They use integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate facilities related to home life, and build an efficient management system for residential facilities and family schedule affairs. . The core is "the thing", first need to have a communication network, can include all hardware, provide the necessary thoroughfare for family information exchange and transmission. Under the overall home network operating system, commands are issued to the corresponding hardware and modules to implement detection and control of home electronic hardware. Externally, home systems require a media platform for external communication, enabling "internal" and "external" communication and communication to meet the needs of remote control, inspection, and information exchange.

In the follow-up "learning" process, the smart home system's computational load is insufficient to support the analysis and storage of large amounts of data. The computing and storage requirements of the smart home system can only be met by external accessories. Cloud computing officially provides low operating غير مجاز مي باشدts so that each can connect to the cloud service center through the Internet. The data it generates is stored and processed by the cloud computing center.

Smart home has been developed in China for more than 10 years, and it has not been developed rapidly until recent years. The main reason is that the function is single, and the degree of intelligence is not high. Users do not enjoy high-tech charm.

Since cloud computing is one of the massive information processing platforms, smart homes have significantly increased their intelligence capabilities and their devices respond quickly. Taking the Z-wave smart home as an example, it now has many functions such as smart appliances, intelligent lighting, smart curtains, audio and video control, and environmental monitoring, and it has achieved convenience. The response speed of each execution instruction is within 1-2 seconds on average, which is convenient and quick. This is because with cloud computing, there is a large storage space, and the analysis and transmission of data are performed rapidly, which greatly increases the speed and naturally increases. Therefore, in the era of smart home, cloud computing technology will become an important support. . With the high degree of development and application of the Internet of Things industry, each item in the future may have its own identification mark, which needs to be transmitted to the back-end system for logic processing. Different levels of data and various types of industry data require strong system backing support. Can only be achieved through cloud computing. Combine all computing resources and storage resources that can be integrated through cloud computing to jointly process requests for global smart home business, and flexibly expand corresponding computing and storage resources through on-demand use, and combine IoT resources as the smart home field. Important support platform.

Nowadays, the attitude of various companies for cloud computing has also changed. The information technology department has never trusted cloud computing to spend hundreds of millions of dollars to deploy cloud storage. Cloud computing was seen as an enabler of technology from the early days and now it is covered by services. Whether the scope, pace of development, or flexibility has brought more benefits to the organization.

As various smart home products will form a small Internet of Things in the home, each smart home system is also a unit in the large-scale Internet of Things. Through cloud computing, it can make home and social networks, news channels, and data analysis. Even the government's decision-making is linked and everything is possible under the support of the cloud. Cloud computing is a trend. In the near future, cloud computing will go deep into every corner of our lives, triggering radical changes in various industries, including healthcare, urban planning, energy, e-retail, and entertainment. It is believed that more smart home companies will combine smart homes and cloud computing organically in the future so that customers can enjoy better and more secure services.
