2、 Disassembly of oppo 65W flash charger

The input end shell is disassembled, the pin and PCB board are connected and powered through AC wire, and both ends of the wire are glued to reinforce the insulation. The components such as transformer, capacitor and inductor on the front of PCB board are glued and reinforced, and there is a white isolation board between the primary stages. The back of the board is provided with a metal radiator and a white isolation board. After removing the isolation board, the main control chip of the power supply spans between the primary stages, and the main heating chip is glued to help heat conduction.

After observing and analyzing the charger circuit, it is found that this 65W original fast charging charger adopts a typical architecture of switching power supply with wide range output, and the output voltage is controlled by the protocol chip. The distribution of components is relatively sparse, so it is not easy to accumulate heat. Let's start from the input to understand the information of each component one by one.

Summary of dismantling charging head net

Oppo reno4 this 65W original quick charging charger is replaced by Huizhou Jinhu Industrial Development Co., Ltd. with smooth surface, round corners and good sense of use. The charger is equipped with 5v/2a and 10v/6.5a gears, which supports maximum 65W output, and is downward compatible with supervooc and vooc protocols, which is applicable to all the fast charging mobile phones in the oppo family.

The charging head network is understood through disassembly that the charger adopts a typical architecture of switching power output in a wide range and controlled by protocol chip. AC-DC part of charger is composed of PI power main control chip sc1738c and generation MOS. The output voltage is controlled by the micro customized vooc flash charging chip of Ruixin. In addition, there is isolation design between the initial stages and the insulation baffle is added; Injection treatment of transformer and capacitor inductor and other components is used for fixing components and auxiliary heat conduction. The whole product from materials to workmanship, all revealed the high quality requirements of oppo.
