Disassembly report: Huawei 25W Mini super fast charging charger

2022-04-02

Huawei recently held a spring conference of whole house intelligence and new products. At the conference, Huawei brought a mini super fast charging charger supporting 25W output, which supports not only SCP and FCP Huawei fast charging protocols, but also QC and PD3 0 PPS fast charge. Huawei's Mini super fast charging charger can provide an ideal fast charging experience for mainstream mobile phones. It is a very competitive fast charging charger.

The charging head network has obtained the Huawei Mini super fast charging charger. Here's a preview of the testing and disassembly of this charger.

The mini super fast charging launched by Huawei adopts a small square shape, which is compact and saves space. The charger has single usb-c output and supports FCP and QC2 0、PD3. 0. PPS fast charging protocol. It also has 5v3a and 9v2 78a, 12v2a, and 3.9-5.9v3a and 3.9-11v2 25A two groups of PPS voltage gears are very good for fast charging compatibility of mainstream mobile phones.

Through disassembly, the charging head network learned that Huawei Mini super fast charging adopts two PCBs, and the transformer adopts plastic frame, which is combined and welded into a whole, with high space utilization and good integration. The charger adopts silijie sy50238 + sy52341 highly integrated switching power supply scheme, and the protocol chip supports a wide range of protocols. Aishi capacitor filter is used internally, the built-in thermistor is used for temperature detection, and TVs is used for electrostatic protection of data pin, which is stable and reliable as a whole.
