Summary of charging head network disassembly

想了想还是信仰比较重要,索尼大法45W PD快充适配器拆解

The Sony 45W PD charger uses a conventional square design, comes with a 1 -meter output cable, and a fixed pink design, but the setting setting is not very friendly to the porous insertion, which will block other jacks. According to the previous observations of the charging head network, the charger of large brands comes with cables is usually not unexpectedly designed. Compared with domestic manufacturers, competitiveness is obviously absent. The charger supports the PD2.0 fast charge protocol, and the output supports 5V3A, 9V3A, and 15V3A three sets of fixed voltage gears, but it can still power the notebook that supports PD fast charging.

想了想还是信仰比较重要,索尼大法45W PD快充适配器拆解

The charging head network learned through disassembly that the charger of Sony uses an irrigation process, which has stronger heat dissipation performance and weather resistance. A built -in thermistor is used to detect temperature rise. The charger uses NXP NXP TEA18362 primary controller+TEA1792 synchronization rectifier controller. The protocol chip uses Yuchuang EJ898P, supports PD2.0 fast charge, and the output uses electrolytic capacitors and solid capacitors to meet long -term use needs.
