![]() ![]() Infineon’s dual port charger reference design application notes include the detailed 2-port USB hub circuit diagrams. ![]() The EZ-PD™ CCG7D is a 2-port USB hub IC specifically designed for dual port hubs, featuring two buck boost converters and full programmability for implementation of load sharing. This has triggered the development of multi-port chargers like 1A1C or 2C designs, 1A1C standing for a charger with one Type-C connector and one Type-A connector. More and more original equipment manufacturers (OEMs) no longer sell the chargers/adapters together with the devices, the end-user demand for aftermarket supply has increased. USB-C simplifies the end-user experience and together with the introduction of GaN devices and increasing switching frequencies it enables more compact and light-weight chargers and adapters. The latest released USB-PD Rev3.1 standard increases the maximum charging power even to 240W. USB-C power delivery (USB-PD) has emerged as the standard for unified and fast charging and for supplying power up to 100W for all kind of mobile devices such as smartphones, tablets, laptops, smart speakers, TVs and others. ![]()
