Nowadays, more and more devices choose to use Type-C interface to replace the previous traditional interface. For example: the mobile phone removed the previous Micro USB interface, and chose Type-C; and many notebooks also canceled many traditional transmission interfaces, and replaced them with Type-C. So why can Type-C replace so many data interfaces, and what are its advantages?
Let's first understand what the previous data transmission interfaces are. Generally, the mobile phone uses the Micro USB interface, which belongs to the transmission interface under USB 2.0; in addition, some non-smart phones use the Mini-USB interface. These two interfaces actually belong to the Type-B category. In addition to mobile phones, devices such as monitors, printers, digital cameras, and mobile hard disks also use Type-B interfaces for data transmission.
Before the Type-C interface appeared, the receipt interface of most notebooks used the USB interface, which actually belongs to the Type-A category, including many desktop computers also have this type of interface. Generally, everyone uses this interface to connect peripherals such as mouse and keyboard, and the interface between the charger and data cable of the mobile phone also belongs to this type.
So what are Type-A, Type-B and Type-C, and what do they look like? We can see it at a glance through the picture below. In fact, everyone should have used every interface. 
After getting acquainted with the appearance of Type-C, let's take a look at how it was produced. As early as 2015, Nokia, the former mobile phone industry giant, released a tablet computer. For the first time, this computer uses the Type-C interface as the data transmission interface, bringing the Type-C interface to the public for the first time. However, due to the decline of Nokia mobile phones, people did not pay much attention to this computer. Just when everyone thought that Type-C would withdraw from the stage of history together with this computer, only two months later, Apple released a brand new MacBook using Type-C as the data transmission interface. Soon, driven by this brand new MacBook, the Type-C interface quickly attracted the attention of the public, and was pushed to the peak of the craze for a while. Seeing this situation, Nokia could only cry silently.
We all know that compared with USB 2.0, there is actually no big difference in appearance between USB 3.0 and USB 2.0. The color of USB3.0 is generally blue, while the color of traditional USB2.0 interface is black. The biggest feature of USB3.0 is that the transmission rate exceeds USB2.0 by a lot.
Since Type-C can replace the USB interface, can it surpass USB3.0 in terms of transmission rate and transmission function?
First of all, Type-C came out with the new USB3.1. So its transfer rate is equivalent to USB3.1. But not all Type-C can have the same transmission rate as USB3.1. At present, there are still some Type-C interfaces on mobile phones whose transmission rate is only at the level of USB2.0.
Secondly, the reason why Type-C has been widely recognized by the public on laptops is because Type-C can replace almost all traditional interfaces. One interface can realize a series of functions such as charging, transmitting data, video interface, and connecting a projector.
Furthermore, compared with traditional interfaces, Type-C has a small appearance. In this era of pursuit of thinness and lightness, Type-C will be the best choice.
Finally, the power supply capability of Type-C is much stronger than that of traditional interfaces. For example, it can achieve a power output of up to 100W. It can also be used to realize two-way power supply function: it can not only supply reverse power to peripherals, but also charge itself, and the charging time will be many times higher than that of traditional interfaces.
It is precisely because Type-C has so many advantages above that it can replace the traditional data interface. So, how to use the TYPE-C interface instead of the traditional DC interface consumer?
LDR6328S is a sink controller compatible with USB PD, QC and AFC protocols. The LDR6328S draws power from adapters supporting USB PD, QC and AFC protocols, and supplies power to the device. For example, the adapter can be configured to output the required power to supply power to small consumer appliances. The LDR6328S is also compatible with conventional USB power adapters.
