With the rapid development of the technology industry and the popularity of smartphones, the market size of power adapters is rapidly expanding.

Power adapters are widely used in various application fields such as information and communication, consumer electronics, and household appliances. With the advancement of technology and the continuous increase in consumer demand, the market demand for adapters is also increasing. According to statistics from market research institutions, the global power adapter market is continuously expanding at a compound annual growth rate of 7.1%. It is expected that the market size will reach 45.8 billion US dollars by 2025, which also means that the power adapter market has broad prospects.

However, although the current adapter market has strong demand, it also faces some problems. In recent years, batteries with a capacity of over 5000mAh have become mainstream. With the increase of mobile phone battery capacity, charging speed has also become an important factor affecting user experience. With the development of fast charging technologies with different brands and protocols, various fast charging protocols have emerged in the market, such as QC, PD, FCP, VOOC, etc. The diversification of this fast charging protocol poses great challenges to product design and development.

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

To solve this problem, a high-power adapter that is compatible with multiple fast charging protocols becomes very important. In this regard, Xinhai Technology fully explores market demand and, with a deep understanding of its adapter application technology, develops and launches the power management chip CPW3301 suitable for adapter applications.

Application of CPW3301 adapter in Xinhai Technology

Generally speaking, the application architecture of fast charging adapters mainly includes three modules: AC-DC conversion module, power control module, and fast charging protocol module. Among them, the AC-DC conversion module is responsible for converting 220V AC power to DC power, the power control module is mainly used to adjust the DC voltage to the voltage required by the phone, and the fast charging protocol module is responsible for shaking hands with the phone to communicate, collecting voltage, current, and various information requested by the phone.

CPW3301 not only integrates power control module and fast charging protocol module, shouldering the core task of the entire fast charging process, but also specifically solves a series of pain points of current power adapters in the market.

Firstly, the power management module of CPW3301 has high integration and rich functionality. This chip integrates two of the three main modules of the fast charging adapter: the power control module and the fast charging protocol module. The power control module is mainly used to adjust the DC voltage to the voltage required by the mobile phone, and mainly integrates CC, CV loop control, NMOS drive, high-precision current sampling, bilateral VBUS discharge, etc.

Secondly, the fast charging protocol module of CPW3301 demonstrates strong compatibility. The product covers various mainstream fast charging protocols on the market, such as PD protocol, PPS protocol, QC protocol, FCP protocol, SCP protocol, AFC protocol, VOOC protocol, APPLE protocol, UFCS protocol, etc. This means that regardless of the brand or model of the phone, a good charging experience can be achieved through CPW3301, meeting the diverse needs of users.

Finally, CPW3301 balances high safety design. The product is equipped with a 12 bit ADC to support multiple protection mechanisms such as OVP, UVP, OCP, OTP, and short circuit protection, effectively preventing the occurrence of power short circuits, overvoltage, overcurrent, overheating, and other situations, thereby providing users and devices with comprehensive safety protection.

In summary, the high integration design of Xinhai Technology CPW3301 reduces the number and cost of peripheral devices, making the overall size smaller and more suitable for modern consumers' demand for lightweight and portability. At the same time, rich fast charging protocols can provide a better fast charging experience for more charging devices. Single C port and 1A1C applications, as well as flexible fast charging protocol combinations, bring convenience to customers with diverse needs.
