In addition, it also has three fixed voltage gears of 5V2.4A, 9V2.22A and 12V1.67A, and a set of PPS voltage gears of 3.3-11V2A.
Second, Jiletang magnetic wireless mobile power disassembly
Detach the fuselage case and snap the edges to secure the package.
The magnetic module is fixed by covering the plastic plate.
The wireless charging coil solder foot cover has an insulated tube.
Remove the coil and attach a protective foam to the back.
The wireless charging coil is wound with Leeds wire winding and gluing in the central area.
The PCB board is fixed with screws, the board is attached with a thermal pad, and the bottom of the battery cell is stuffed with foam for cushioning protection.
Remove the screws to remove the PCB board and battery cell, the other side of the board is also pasted with a blue thermal pad to help the main control chip dissipate heat, capacitors, inductors glue reinforcement.
The front of the PCB board is also equipped with a mobile power main control chip, a lithium battery protection chip, and an LED indicator.
A wireless rechargeable capacitor is soldered on the back.
The main control chip of mobile power adopts Yingjixin IP5568, which is an integrated wireless charging TX/RX, QC2.0/QC3.0/SCP output fast charging protocol, FCP/AFC/SFCP input and output fast charging protocol, MTK PE+ 1.1&2.0 output fast charging protocol, USB-C/PD2.0/PD3.0 input and output protocol, USB-C PD3.0 PPS output protocol, compatible with BC1.2/Apple/Samsung mobile phone, synchronous up/down converter, Lithium battery charge management, battery charge indication and other multi-functional power management SOCs provide a complete power solution for fast-charging mobile power.
IP5568 can support USB-A x 2, USB-B, USB-C four USB ports at the same time, use any one USB port alone can support fast charging, and only support 5V output when using two or more output ports at the same time. Ip5568 supports wireless charging and USB port at the same time, the USB port also supports input and output fast charging function.
It is worth mentioning that The INJIXIN IP5568 is the world's first single-chip SoC that integrates 22.5W wired full-protocol fast charging mobile power supply and 15W wireless fast charging, and the charging head network has previously reported in detail on the high-performance high-integration power management SOC of Yingjixin.
In addition, in-house IP5568 has also passed Qi certification. WPC official website page shows that it has passed the latest Qi V1.2.4 version certification, Qi certification ID of 7485, registration type of transmitter, certification type of BPP certification, power 5W. With the blessing of Qi certification, the wireless charging compatibility and security of the product are more secure.
Charging head network learned that Yingji core IP5568 has achieved mass production and listing, but also by Sule 10000mAh magnetic wireless charging mobile power supply, Greenlink 10000mAh magnetic wireless charging mobile power supply, Pengyuansheng 5000mAh 20W magnetic wireless charging mobile power supply, Quanhan 22.5W super fast charging + 15W wireless charging mobile power supply and other products.
In addition, The Yingjixin fast charging chip can also be used in various charging fields such as chargers, car charging, energy storage power supplies, etc., and is used by more than 100 products of well-known brands such as Xiaomi, Beijing Tokyo, Huawei, Samsung, Tesla and so on.
