Recently, http://www.chongdiantou.com/ learns from a supply chain that Injoinic, a well-known fast charging chip brand, releases the first 45W mobile power bank SOC chip IP5388 in the industry. 45W boost control and buck control and various input protocol and output protocol can be achieved with only a chip. It breaks through the ceiling limited by power of traditional single-chip mobile power bank for the first time. It plays an important role in facilitating the development of mobile power products towards high integration and high power.

From the DEMO board developed by the SOC chip of Injoinic 45W fast charging mobile power bank, it can be seen that there is only a IP5388 chip on the front besides necessary inductors, capacitors and interface switching MOS, and its peripheral circuit design is very simple.

There are few components on the back of PCB, which are almost negligible.Injoinic Releases the First 45W Mobile Power Bank SOC Chip IP5388-askpower

Such a simple PCB layout is entirely attributed to the adoption of IP5388. It is learned that Injoinic IP5388 supports fast charging output protocols such as QC2.0, QC3.0, QC3.5 and MTK PE+1.1&2.0, and supports fast charging input protocols and output protocols, such as AFC, FCP, SCP, VOOC and SFCP. Its USB-C port supports fast charging input and output protocols such as PD2.0 and PD3.0. Its USB-C port supports PD3.0 PPS fast charging output. It is compatible with BC1.2 and charging of Apple mobile phones.

At the same time, Injoinic IP5388 integrates synchronous bidirectional buck converter and boost converter, lithium battery charging management, battery power indication and other functions, and supports 2-4 series batteries. The synchronous switching boost system can provide the maximum output capacity of 45W. In application, only an inductor and very few peripheral devices are needed. It effectively reduces the size of the whole scheme and reduces the cost of BOM.

Through the built-in power calculation method, Injoinic IP5388 can accurately obtain battery power information. The battery charge curve can be customized to accurately display the battery charge. It supports 4 LED power display and various digital tube power display such as 88 and 188; Support lighting function.
