Disassembly report: Gushi technology 25W PD fast charging charger

2021-09-22

The continuation of the non standard charger strategy for Apple's iPhone 13 new machine will bring a new round of fast charging market boom. Therefore, Shenzhen Gushi Technology Co., Ltd. recently launched a 25W PD fast charging charger gs-w25a0929 for customers to choose, which is convenient for rapid listing and seize the market opportunity.

The charger is equipped with a single usb-c interface. In addition to three groups of conventional fixed voltage gears of 5V, 9V and 12V, it also has two groups of PPS voltage gears of 3.3-5.9v3a and 3.3-11v2.5a. It has good compatibility and can meet the daily fast charging needs of iPhone 13. The following charging head network will disassemble this charger in detail to see how the materials and workmanship are.

For those who want small volume fast charging, Gushi technology also has mini 30W gallium nitride fast charging charger, mini 20W PD fast charging, 20W biscuit charger and other styles to choose from.

Gushi technology 25W PD fast charging charger is very similar to Apple 20W fast charging, but the input end is equipped with a protruding shell and fixed national standard pins. The overall design of the fuselage is very simple, which can meet customers' differentiated customization. The charger has passed the national CCC certification with reliable quality, supports 100-240V wide range voltage input, and is compatible with the mainstream fast charging protocols of QC, AFC, FCP, PE, PD and PPS to meet the requirements of consumers.

Through the disassembly of the charging head network, it is learned that the charger adopts the Biyi micro kp22315wg + kp41262sg switching power supply scheme, which is a fast charging scheme tailored for the 20W ~ 30W charger market. It has the characteristics of high integration, high efficiency and reliable performance. In addition, yingjixin ip2723t protocol chip is used to control the output voltage, and Yongming small volume fast charging capacitor is used for filtering. The overall material is good. In addition, the front components of the PCB board are also glued and reinforced and insulated, and the workmanship is also very exquisite.
