The fully shared architecture controls multiple charging ports simultaneously mainly through a Multi-Port Controller with the following features.
Product is suitable for 20W~30W low power fast charging applications
Ultra small size for easy portability
Any port of the product supports fast charging when working alone, and supports 5V charging when working at the same time

Fully independent architecture
Fully independent architecture through two or more Port Controller to achieve multi-port fast charging, this architecture is more used in high-power applications. Its features are.
The product is suitable for medium and high power applications of 65W and above, and can meet the charging needs of more types of electronic products
Full power output when either port is used alone; multiple ports work simultaneously to support fast charging
Products can be intelligently distributed power, energy efficiency is high

The use of fully independent architecture of multi-port fast charging products, similar in design to stacking blocks, can be extended to 2 and more. However, it is because of this form of building blocks that predestines its products to be larger in size. In this architecture, if the DCDC 2 times down power (as shown below), the product size can be reduced, but the efficiency will be slightly weaker compared to before.

The semi-independent architecture controls multiple ports through DCDC+Port Controller, which is mainly used for 30W~65W products. Its features are.
The product is suitable for 30W~65W and other small and medium power applications
The product supports fast charging for any one port alone; when working with multiple ports, C1 port always supports fast charging

Check the ranking of fast-charging power adapters sold on some mainstream e-commerce platforms, you can find that the top-ranked charger power is basically 20W; at the same time, check the ranking of power adapters for tablet PCs, and find that the power is mostly concentrated in 65W. For different application scenarios and fast-charging power requirements, choose a suitable multi-port fast-charging design that can effectively reduce costs and improve performance and efficiency.
The upcoming HUSB365, a dual-port USB Type-C and USB Type-A controller, is designed for small to medium power (15W~65W) multi-port fast charging applications, supporting 1A1C or 2A2C and more A+C port multi-port fast charging designs using a fully shared architecture. Its ultra-small package size (4 mm x 4 mm QFN-24L) also facilitates the design of miniaturized multi-port fast charging sources.
