2021-10-30

Shenzhen Zhongxian Innovation Technology Co., Ltd., founded in 2009, has been deeply engaged in the power supply industry for more than 10 years. It has an experienced team, focusing on the R & D, production and sales of QC, PD and Gan chargers. The company invests heavily in new product research and development, focusing on quality control. The products cover multiple port charging, wireless charging, car charging and other series. In the Gan product series, more than ten products in multiple power segments such as 30W, 65W, 78W, 100W, 130W and 150W have been launched, which have been widely recognized by the market and consumers.

Recently, the charging head network has obtained a 65W gallium nitride fast charging charger from Zhongxian, which is equipped with folding pins and 2c1a interface. It is small and can support the fast charging of large and small devices such as laptop, tablet and mobile phone, so as to meet the dual requirements of users for the portability and high performance of the charger. It is understood that the product has strictly passed the en62368 certification, and the temperature rise under various power states is controlled within the specification. The charging head network also learned that the charger has built-in jw1515h + jw7726b full set of high-frequency QR power supply scheme of jw1515h + jw7726b, a well-known manufacturer in the industry.

The 65W gallium nitride fast charge of Zhongxian adopts square shape design, focusing on small and portable, high-power fast charge and simultaneous fast charge of multiple devices. It is very suitable for groups who often travel abroad. The three interfaces of 2c1a equipped with the charger are compatible with QC, AFC, FCP, SCP, pe2.0, pd3.0 and PPS, and have good compatibility with equipment of big brands such as apple, Huawei and Samsung.

In addition, the products have passed FCC and CE certification, with reliable quality. At the same time, if customers have needs, they can also pass CCC safety certification to facilitate customers' sales in China. Zhongxian can provide comprehensive and thoughtful services.

Through the disassembly of the charging head network, it is learned that a large-area heat conduction pad and heat sink are pasted on the front and back of the charger module to ensure the heat dissipation performance of users when charging the equipment with high power. The output capacitance, inductance and other devices are also insulated to ensure safe use.

The charger adopts jw1515h + jw7726b high frequency QR switching power supply scheme, with innoseco inn650d02 gallium nitride power switch tube and Gufeng synchronous rectifier tube. Both DC-DC circuits adopt Zhirong sw3516h scheme. Yongming electrolytic capacitor is used for input filtering, and solid-state capacitor is used for synchronous rectification output and secondary step-down output filtering.
