Disassembly report: Netease Zhizao 65W 2c1a gallium nitride charger

2022-02-28

Since the outbreak of gallium nitride fast charging, Netease Zhizao has also launched a number of gallium nitride chargers. Previously, the charging head network has disassembled the brand's 61W single C-Port and 65W 1a1c double port gallium nitride chargers, but it has been a long time.

Recently, the charging head network has obtained the 65W 2c1a gallium nitride charger made by Netease intelligence. The shape and configuration are very mainstream. It supports the full mainstream fast charging protocol and the 45W + 20W dual port output strategy. Next, the charging head network continues to disassemble this charger in detail to see how the product is doing.

Netease Zhizao's 65W 2c1a gallium nitride charger is a further supplement to the brand's gallium nitride fast charging products, with more interfaces and more comprehensive compatibility protocols. Both C ports support 65W fast charging, power blind plug-in and easy to use. They also support 45W + 18W / 20W dual port fast charging at the same time, meeting the fast charging needs of apple, Huawei, Xiaomi and other brand equipment.

After dismantling the charging head network, it is found that this charger adopts the architecture design of classic high-frequency QR switching power supply and two DC-DC secondary step-down circuits. The switching power supply controller is a classic combination of ansenmey ncp1342 + MPs mp6908a, with nano nv6115 gallium nitride chip and Shilan micro synchronous rectifier. Both step-down output schemes adopt Zhirong sw3518s and Yongming small volume fast charging capacitor for input and output filtering, with solid and reliable materials.
