2022-05-04

Netease smart manufacturing is a hardware brand under Netease, including small household appliances in many categories, such as patch panels, speakers, headphones, mobile phone accessories, computer office, battery power supply, household appliances and personal health care. Before charging head network, many Netease smart manufacturing products have been disassembled.

With the release of iphone13 series mobile phones, the fast charging power has been increased from 20W to 27W. Higher power chargers are needed to meet the fast charging demand of mobile phones. The power of mainstream chargers has also been increased from 20W to 33W, which can not only meet the fast charging demand of Apple mobile phones, but also meet the PPS fast charging demand of Android mobile phones.

Previously, the charging head network evaluated the Netease smart 33W dual port gallium nitride charger, which is small in size and has 1c1a dual interface. The fast charging protocol supports comprehensive charging of mobile phones and notebooks. At the same time, it supports traditional fast charging and multi-purpose. The following charging head network will bring you the disassembly of this charger to see how the interior of mini fast charging is designed.

The shell adopts the alternating design of bright surface sanding process, which is very characteristic. The charger is not only equipped with 1a1c interface, but also three-dimensional only 34 * 31 * 31mm. In addition, the interface supports QC2 0/3.0、AFC、FCP、SCP、PE2. 0、PD3. 0. PPS fast charging protocol can fully meet the requirements of consumers in terms of volume and performance.

Through the disassembly of the charging head network, it is learned that the charger adopts a set of sc3021d + sc3503 high-frequency QR switching power supply scheme of Nanxin, together with inn650da04 gallium nitride power switch tube of innoseco and synchronous rectifier tube of Shilan micro, and the dual port output is controlled by Intel ip2726 protocol chip. Yongming small volume fast charging capacitor for input and output filtering. The overall material and workmanship are good.
