Fast charge protocol is a big problem. The brand mobile phones each have their own protocol, conflicting. This allows the charger, charging car manufacturers and mobile power loss. From the perspective of power management, all our products are very different in terms of efficiency, temperature. Fast charge technology to keep up with demand for mobile phones - low efficiency, high temperature, and poor reliability. In addition, power systems become more complex, there are a variety of interfaces, and continue to update. The logic of the system becomes very complicated, the phone is also very complicated, so difficult to make a great product will be an order of magnitude than ever before.
Traditional power chips, as much as several kinds of device type. For different topologies, power supply design engineers need to constantly choose from, and often may not want to pick IC-- patched, certified, you will encounter a variety of problems. Therefore, the industry hopes to launch reconfigurable power chip.
The so-called reconfigurable power chip, that is, can be quickly customized power chip based on the user's idea - through a variety of methods to quickly customize software and hardware to meet customer demand for power chip under the premise of not taped, and even with system management functions. Some hope that the power of small volume, the need is certified, it is desirable to power supply design can be more flexible.
Traditional power development time required about two years, but by the power of reconfigurable chip design, development time is shortened to one week. It can meet different architectures, such as boost, buck, buck, multi-output, multi-phase, etc., all of which control details can be customized. At the same time, in many segments of years, before there are a lot of power on the IC, and now it is with the single-chip solution to achieve the overall system management. In the field of power and control, it has also been a lot of progress and breakthroughs.
Moore's Law with us for a long time to come. Now we have to 7nm node, CPU faster and faster, but the semiconductor process and then go on more and more difficult, including research and development costs and overall power consumption. It is not Moore's Law, the chip industry to the dead end gone? Chip later how to go? This is a topic in the industry is now widely discussed.
On the other hand, the smart phone 2-fold increase computing power, but the efficiency (degree of ease of use, including communications, applications, and various micro-channel) is only increased by 15%. There was a big gap between the needs and direction of development of semiconductors. So we need to think about whether the semiconductor process development truly meet the general needs of the public?
CPU, power supply chips, RF chips, analog chips have made "reconfigurable" concept, why not?
CPU, power chip, RF chip, an analog chip have proposed the concept of "reconfigurable" in. Why a sudden, these different areas have emerged the concept of reconfigurable, there are profound reasons behind it. "Human needs become more diversified, individualized, differentiated (such as our mobile Apple, Huawei, OPPO, etc.), so the market will be more fragmented and varied, including fast charging, wireless charging, new energy. the terminal application to IC-based, which results in IC designs become more complex. this is the origin of reconfigurable design power of the chip. "Mr. Wu said.
Easy can help microelectronics customers can quickly customize power supply IC. Involving applications include mobile phones, tablets, fast-charge adapter, fast charging mobile power, fast charge car charger, laptop, car starting power, electric tools, Bluetooth headsets, Bluetooth speakers, wireless charger, power simulation, unmanned aerial vehicles, POS machine, BMS and so on. "You rarely see IC companies involved in so many directions, but also because it is reconfigurable. Requirements of these directions vary greatly, from power, pressure to control method, management system requirements are not the same." Mr. Wu expressed.
IPhone 8 after the listing, PD is expected to become the mainstream fast-charge agreement, however differences in protocol, performance, interfaces, etc., resulting in a product designed to enhance the difficulty of magnitude
Fast-charging power supply is a good opportunity for development. With other smart phones generally adopted after the fast charge, Apple has finally now also supports the fast charge. 8 Apple market, Apple phone, tablet, laptop support all protocols PD, PD is expected to become the mainstream fast charge protocol. All mobile phones have achieved a fast-charge, fast charge industry usher in the explosive market. "Yi could be the world's only full line of products to support Apple's single-chip PD fast charge and car charger mobile power solutions and is the only fast charge compatible with all mobile phone chip program, including Apple." Mr. Wu said.
Fast charge protocol is a big problem. Apple, Samsung, Huawei, OPPO phone brands each have their own protocol, conflicting. Millet, Jin, Meizu also were supported by Qualcomm or MediaTek agreement. This allows the charger, charging car manufacturers and mobile power loss. Various protocols are not compatible hampering the development of the industry.
From the perspective of power management, 3V switch 12V / 18W boost IC also reach very good performance. Each company's products in terms of efficiency, temperatures are still very different. However, the industry's fast-charging power has reached 100W, mobile phone fast charge power reached 24W, Huawei has reached 40W. Fast charge technology to keep up with demand for mobile phones - low efficiency, high temperature, and poor reliability.
"Buck-boost IC used in the PD, TI, Intersil, Linear and other companies have, but the price is very little good, but also hindered the development of PD market. Protocols variety of power system becomes more and more complex that has an interface port a, B port, C port, Lightning port, and so are many, and will continue to update the logic of the system becomes very complicated, the phone is also very complicated, so difficult to do a product will be larger than ever a order of magnitude. "Mr. Wu said.
Reconfigurable power chip can be upgraded quickly adapt to market changes without changing the circuit board
Fast charge can easily comprehensive coverage mobile power line, car charger, the adapter strip and the like. Temperature and efficiency is also doing very well. Meanwhile, Yi is currently the only company able to support all protocols of fast charge IC companies. There are more than 100 fast-charge device (cell phone) can support, and also supports all PD phones and tablets, and is a single-chip PD solution.
Apple now supports all accessories PD. Therefore PD may become the mainstream industry, and even electric bikes are using PD may be charged. In addition, not only is Apple's mobile phone, all phones can support a program easy to use energy.
Further, power chip architecture is reconfigurable. If the speed-changing market, three-month new requirements emerge, usually chip companies can not keep up, and we will do our best to help clients make them compatible headache. For example, iPhone 8 on the market, if there is no good to think ahead related needs, could result in product backlog. But if it is easy to program using energy, you can put the entire product upgrades without any change of the circuit board to quickly adapt to market changes and seize market opportunities.
Here is the program easy to demonstrate energy.
"EDP3010x actually a buck-boost chip, but it also integrates a variety of management. It is in terms of pressure and lifting Linear, TI is completely different. We have our very good algorithm, most notably, close to the input and output when there is no fluctuation switching, very smooth, which is the traditional analog IC is very difficult to do that. "tread added," and it is a single-chip solution, PD-compatible protocol, and with cell balancing. "
