Lightning interface has its own defects and can no longer comply with the development of the industry

Apple's new mobile phone iPhone14 still uses Lightning interface, but this does not prevent Apple from replacing all of them with USB-C in the future, because Lightning interface has been unable to comply with the development of the industry due to the following defects.

First, the Lightning port can transmit up to 480Mbps, which is only about the speed of USB2.0. In 2019, USB4 is already 40Gbps. Second, Lightning port supports 36W fast charge at most, while PD3.1 under USB4 is already 240W. Third, the Lightning interface has no video transmission function.

So Apple's switch to USB-C is a trend, the era of unified charging ports is coming. Apple's switch to USB-C will not only save electronic waste, but also enable high-speed data transfer to improve the user experience, and eventually lead to a unified charging protocol. It can be predicted that Apple will support more and more fast charging power in the future.

schitec has laid out in advance a number of 20W~100W fast charging integrated solutions adapted to USB-C. The self-developed SSR+SR+ protocol chip is used in all the schemes, which can drive Si MOS or GaN power tube. Customers can choose the sealing solution to make the product miniaturization or take advantage of their own supply chain to choose the separation solution.
