Recently, from http://www.chongdiantou.com/, it is learned that highly- integrated fast charging power chip of Mix-Design officially enters  supply chain of Luxshare. Boshuo Technology, a wholly-owned subsidiary of Luxshare, develops the first ultra-simple 18W fast charger successfully based on power chips of Mix-Design. The simplification of PCB is just equivalent to that of traditional 5V/2A chargers, which greatly reduces design difficulty and production cost of 18W fast chargers. Thus it becomes the first choice for replacing traditional 10W chargers with 18W fast chargers.

The 18W fast charger produced by Boshuo Technology has a small volume. It is portable and has strong compatibility. After tested, it is found that this charger supports Apple 2.4A, Samsung 5V/2A, DCP protocol, and fast charging protocols such as QC2.0/3.0, AFC, FCP, MTK PE2.0+. It can meet fast charging of many mobile phones such as Huawei, Xiaomi, Samsung, and is very practical.

According to the disassembly of http://www.chongdiantou.com/, it is learned that only a PWM master chip of SOP-7 is used in the primary side of this charger, and only a SOP-8 chip is used in the secondary side. The two chips are from Mix-Design. There are only necessary patch resistors  in the periphery of the chip. Thus the chip is very simple.

Compared to PCB plate of traditional 5V/2A charger, it can be seen that there is no obvious difference between the 18W fast charger that is based on the full set of power supply chips of Mix-Design and it in some aspects such as structure layout and the number of components. With an additional optocoupler that is used for fast charging voltage feedback, the simplification of the scheme completely subverts tradition.

The secondary chip MX5461 integrates synchronous rectification controller, synchronous rectification MOS tubes and protocol identification function. It can support many protocols such as QC3.0/2.0, AFC, FCP and MTK PE2.0+, and passes Qualcomm QC3.0 fast charging certification. It is worth mentioning that Mix-Design MX5461 also supports mobile phone removal and quick discharging. A chip can achieve all functions of the secondary side.

The summary of http://www.chongdiantou.com/

With the popularization of fast charging technology, the cost of fast charging of mobile phones is decreasing year by year. As charging of mobile phones gradually enters the national fast charging stage, traditional 5V2A charger can not meet the market demand. 18W fast charger is expected to become the standard configuration of low-end smart phones in the future, and its market demand is huge.

Simplifying complicated things is in line with the consistent product characteristics and research and development concept of Mix-Design. The 18W fast charging scheme of Mix-Design achieves a very simple PCB periphery through highly-integrated chip design. For fast charging power manufacturers, it is not only easy to be developed easily, but also has a cost advantage. Therefore, it has become an excellent solution to replace traditional 5V2A charger with fast chargers in the future.

The highly-integrated 18W fast charging scheme of Mix-Design  successfully enters the fast charging supply chain of Luxshare and achieves mass production and shipment, which on the one hand confirms the excellent performance of the scheme, and on the other hand reflects research and development level of Mix-Design. This scheme is expected to be seen in the fast charger of inbox in the future.
