2021-04-26

Zendure recently launched a new 65W gallium nitride charger - superport S3 pro. The charger continues the Roman column design and is equipped with foldable pins and popular 2c1a interface. At first glance, many people will think it is no different, but after comparison, it is still very different.

Although zhengtuo 65W gallium nitride charger superport S3 has been made very small, the pro version is smaller. As a multi port charger, the power density even reaches 0.97w/cm ³， It's very small and portable. Secondly, it supports 45W + 20W dual port charging strategy, which can meet the fast charging requirements of MacBook and iPhone 12 at the same time. Next, the charging head network will disassemble this new product in detail to see the specific design materials.

Zhengtuo's new 65W gallium nitride charger superport S3 Pro continues the Roman column ID design in appearance, but its volume is smaller, and its performance also keeps up with the current 20W hot market, supporting the dual fast charging demand of iPhone 12 and notebook. In addition, the charger supports mainstream fast charging protocols such as QC, AFC, FCP, SCP, pe2.0, PD and PPS. The overall compatibility is very good, which can meet the fast charging needs of most devices on the market. The dual C port supports power blind insertion, and is easy to use.

Through the disassembly of the charging head net, we know that as a columnar charger, the classic three-stage layout design is adopted in the interior, with distinct layers, and small boards are set at the input and output ends, making full use of the internal space. Secondly, the charger uses switching power supply and two-way DC-DC architecture, which is also very typical.

The switching power supply is composed of the main controller of Anson and nv6115 gallium nitride power chip, and the synchronous rectifier controller of MPS and Weizhao rectifier. The scheme is mature and reliable. The two-way secondary step-down circuit at the output end adopts Zhirong sw3516h + Ruijun ruh4040m2, and the overall material is mainstream.
