Is the first Gan wall plug worth 158 yuan? Disassembly of zhuofeihang 45W wall plug

2021-07-12

Recently, the charging head network got zhuofeihang 45W gallium nitride ultra fast wall charging. Although there are more and more types of sockets with USB module, this one is more excellent. It is the first wall plug with gallium nitride fast charging in the market. It is equipped with 1a1c USB interface and supports 45W and 18W fast charging respectively. The whole socket can charge up to four devices. Now we will disassemble it in detail to see how to design it.

Zhuofeihang's 45W Gan fast charging wall plug is the same size as the traditional 86 panel, which can be inserted into 45W high-power charger module thanks to Gan blessing and clever vertical layout design. Equipped with 1a1c interface to support QC, AFC, FCP, SCP, PD mainstream fast charging, compatible with new and old devices, directly meet the fast charging needs of mobile phones, pen phones and other devices. Products are white, black, gold three styles, can adapt to more styles of living rooms, hotels and other places.

Through the disassembly of the charging head network, it is found that there are two slots in this socket, which are respectively used to install the AC pin copper and the charger module. There is a plastic plate between them, and the two are connected by wires. The switching power supply of the charger adopts the mainstream high frequency QR fast charging scheme of Anson ncp1342 + MPs mp6908a, with nano micro nv6125 Gan power chip and Wandai synchronous rectifier. IP 2726 is used for 1a1c protocol, and MPs mp2491c is used for usb-a output. Yongming kcx and NPX series small volume fast charging capacitors are adopted to help the charger module further compress its size.
