Adapter application case based on Core Sea Technology CPW3301

2024-03-01

With the rapid development of the technology industry and the popularity of smartphones, the power adapter market is expanding rapidly。

Power adapters in information and communication, consumer electronics, household appliances and other application fields have a wide range of applications, and with the progress of science and technology and the continuous improvement of consumer demand, the market demand for adapters is also increasing。According to statistics from market research institutions, the global power adapter market is growing at a compound annual growth rate of 7.The rate of 1% continues to expand, and it is expected that by 2025, the market size will reach 45.8 billion US dollars, which also means that the power adapter market has broad prospects。

However, although the current adapter market is in high demand, it also faces some problems。In recent years, batteries above 5000mah have become the mainstream, and with the increase of mobile phone battery capacity, charging speed has also become an important point affecting the user experience。With the development of fast charging technology of different brands and different protocols, various fast charging protocols have appeared on the market, such as QC, PD, FCP, VOOC and so on。This diversity of fast charge protocols has brought great challenges to the design and development of products。

In addition, factors such as fast charging efficiency, safety, volume, and compatibility are also important considerations for users when choosing adapters。

In order to solve this problem, a high power adapter compatible with a variety of fast charge protocols is very important。In this regard, Core Sea Technology fully explored the market demand, and with its in-depth understanding of adapter application technology, developed and launched a power management chip CPW3301 suitable for adapter applications。

Core sea technology CPW3301 adapter application

Generally speaking, in the application architecture of the fast charge adapter, it mainly includes three modules, such as AC-DC conversion module, power control module, and fast charge protocol module。Among them, the AC-DC conversion module is responsible for converting the 220V AC power supply to DC power supply, the power control module is mainly used to adjust the DC voltage to the voltage required by the mobile phone, and the fast charge protocol module is responsible for shaking hands with the mobile phone, collecting the voltage and current applied by the mobile phone and various information。

CPW3301 not only integrates the power control module and the fast charge protocol module, shoulders the core task of the entire fast charge process, but also specifically solves a series of pain points of the current power adapter on the market。

First of all, the CPW3301 power management module has a high degree of integration and rich features。The chip integrates two modules of the three modules of the fast charge adapter: the power control module and the fast charge protocol module。The power control module is mainly used to adjust the DC voltage to the voltage required by the mobile phone, which mainly integrates CC, CV loop control, NMOS driver, high-precision current sampling, bilateral VBUS drain, etc。

Secondly, CPW3301's fast charge protocol module shows strong compatibility。The products cover all kinds of mainstream fast charge protocols on the market, such as PD protocol, PPS protocol, QC protocol, FCP protocol, SCP protocol, AFC protocol, VOOC protocol, APPLE protocol, UFCS protocol and so on。This means that no matter what brand or model of mobile phone, you can obtain a good charging experience through CPW3301 to meet the diverse needs of users。

Finally, the CPW3301 is designed for high safety。12-bit ADC is built in to support OVP, UVP, OCP,OTPMultiple protection mechanisms, such as short circuit protection, effectively prevent the occurrence of short circuit, overvoltage, overcurrent, overheating, etc., so as to provide a full range of safety protection for users and equipment。

All in all, the highly integrated design of CPW3301 reduces the number and cost of peripheral devices, making the whole machine smaller and more suitable for modern consumers' needs for lightweight and portable。At the same time, the rich fast charge protocol can make more charging devices have a better fast charge experience, single C port and 1A1C application and flexible fast charge protocol combination, bring convenience to the diversified needs of customers。

Smart PD development ecology of Core Sea Technology

For the terminal brand, CPW3301 has greater market development potential with its unique design and innovative technology。For the secondary development of brand customersThe Smart PD development ecology of Core Sea has the advantages of rich resources, flexible and compatible protocols, rich reference materials, efficient and easy to use development tools, etc., which can help brand customers to simplify product design, reduce development costs, and further enhance market competitiveness。

As the first company to launch the USB PD fast charge protocol chip in China, Chipsea participated in the formulation of China's fast charge industry standard UFCS。In recent years, the company has launched a number of PD fast charge flagship new products for various subdivided application fields, and strives for excellence in security, ease of use, etc., achieving a series layout of PD fast charge products in the whole field, which can provide more targeted systematic solutions for customers' terminal products PD fast charge applications。
