Recently, Shenzhen Chengyue Electronics Co., Ltd. launched a mini 20W PD fast charging charger with a small square shape. The input terminal can be equipped with pins of Bank of China, American regulation, British regulation and European regulation, and has passed the corresponding safety regulation certification. In terms of performance, it supports multiple mainstream fast charging protocols such as QC and PD, and has good compatibility. It supports iPhone 12 20W fast charging. Next, the charging head network will disassemble this charger in detail to see how the internal materials are used.

This mini 20W PD fast charging charger of Chengyue electronics is compact and simple, which is convenient for customers to make differentiated customization. In addition, it has passed CCC certification and reliable quality. The charger supports multiple fast charging protocols of QC, AFC, FCP, SCP and PD, and has three groups of voltage gears: 5v3a, 9v2.22a and 12v1.66a. It can not only be used for iPhone 12, but also meet the daily fast charging needs of other brands of mobile phones.

According to the disassembly of the charging head network, the charger adopts the combined welding design of two small plates, and the isolation plate is set between the primary stages of components. In addition, the high integrated fast charging scheme of Biyi micro kp22308wga + kp41262 and tiandeyu jd6606s protocol chip are used to control the output voltage, and the performance and quality of the scheme are reliable. In addition, Junkang electrolytic capacitor and Yongming SMD solid-state capacitor are used for filtering to help the charger realize miniaturization.
