Disassembly report: Jinxiang 65W 2a2c four port fast charging gallium nitride charger

2021-10-20

Recently, the charging head network obtained a 65W gallium nitride fast charging charger from pilot Jinxiang, which has passed the CE certification. It is a product for the overseas market. It is equipped with removable power cord, 2a2c four interfaces, and can charge up to four devices at the same time. It is positioned as a desktop charger.

The four interfaces of the charger support fast charge output and are compatible with all mainstream fast charge protocols such as QC, PD and PPS on the market. In addition, the two types of interfaces also support blind plug-in, 65W fast charge and a variety of multi interface combined charging strategies. They not only have good performance, but also are very convenient to use. Let's continue to disassemble this gallium nitride fast charging in detail to see how the materials are made.

Jinxiang desktop charger adopts the popular square column design, and the fuselage is very simple, which can meet customers' differentiated customization. As a desktop charger, it is equipped with up to 4 USB interfaces. Being able to charge four devices at the same time is one of its advantages. In addition, the design makes the output performance of the two types of interfaces exactly the same. When using a single port, there is no need to deliberately distinguish the interfaces. It can be inserted blindly, which is very convenient.

In addition, thanks to the use of Zhirong sw3516h scheme, the performance of this charger is very good. It supports QC, AFC, FCP, SCP, pe2.0, pd3.0 and PPS all mainstream fast charging protocols, and has a variety of fast charging output strategies. For example, it can be used to fast charge Mac and iPhone 13 at the same time, so as to fully meet the daily charging needs of users.

Through the disassembly of the charging head network, it is found that the four port output of the charger adopts the three-way Zhirong sw3516 secondary voltage reduction scheme, which not only ensures the performance of the interface, but also benefits from the high integration of sw3516. Even if four interfaces are equipped, the circuit design is very simple and concise, which solves the common problems of engineers such as how to layout and distribute power.

The charger also adopts the popular ansenmey ncp1348 + MPs mp6908a high-frequency gallium nitride scheme, with innoseco inn650d02 gallium nitride power tube and zhenmaojia synchronous rectifier, and uses Yongming small volume fast charging capacitor for input and output filtering. In addition, the internal glue filling treatment of the charger can improve the heat dissipation performance and weather resistance, so as to ensure the quality and reliability of the product.
