In the past two years, gallium nitride has developed rapidly in the field of consumer power supply. Whether it is a cost-effective high-frequency QR flyback topology, a high-performance active clamp flyback, or a 100 watt high-power LLC, new gallium nitride fast charging products on the market have been emerging in endlessly.

Of course, the maturity of technology will also make the performance and selling points of products face the problem of homogenization. In order to seek more differentiation of products, power supply manufacturers are also racking their brains. For example, recently, the charging head network has obtained a new 65W gallium nitride fast charging product launched by Tiejia. In addition to the advantages of the current mainstream gallium nitride charger, such as compact and portable, high-power output and multi device support, it also adds the wireless intelligent interconnection function. Users can connect the charger through app, view and set the parameters of the charger, so as to make the charger enter the intelligent era.

Not long ago, the charging head network has also evaluated the performance and basic functions of Tiejia charger. Today, we will continue to share its disassembly and take a look at how the charger can be connected to app is designed. Previously, the charging head network also disassembled an armored 20W PD fast charging charger.

In terms of appearance, the shape of Tiejia 65W gallium nitride fast charging is similar to that of common gallium nitride fast charging products on the market. The long body is equipped with folding pins and three interfaces of 2c1a, and is equipped with status indicator lights. The volume is much smaller than that of traditional power devices. In terms of performance, it is also at the mainstream level in the industry, compatible with a variety of mainstream fast charging protocols on the market, and supports double C-Port blind plug output 65W and multi port power intelligent distribution function.

The most special feature of this charger is the addition of Bluetooth wireless connection function. Users can realize power distribution, output power, power failure, control indicator light and other operations on the mobile phone through app control. It is very convenient.

According to the disassembly of the charging head network, the charger of Tiejia is based on the mainstream switching power supply + secondary step-down architecture in the industry. The switching power supply part adopts ncp1342 + gallium future Gan devices and adopts Xinmao micro synchronous rectifier controller. The output of the three interfaces is composed of two secondary step-down circuits, which are controlled by Zhirong sw3518s; In addition, a Bluetooth module is added to realize the intelligent connection and output control between the charger and the mobile phone app.
