USB-C adapters and chargers
From high power density to cost/performance - meeting any of your requirements
Avoid complexity, incompatibility, and shorten time-to-market with Infineon’s broad portfolio of high-quality USB-C PD solutions. They will help you break through the barriers in fast charging designs at a competitive cost.
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. The latest released USB-PD Rev3.1 standard increases the maximum charging power even to 240W.
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.
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.
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. 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. Infineon’s dual port charger reference design application notes include the detailed 2-port USB hub circuit diagrams.
Making use of the highest USB-PD power rating requires specific USB E-Mark cables that support a maximum current of 5A , in contrast to standard cables limited to 3A.
Infineon offers a variety of charger reference designs and related USB charging schematics based on quasi-resonant (QR), ZVS and hybrid flyback operation, for different power levels and power density requirements. Our innovative single- and dual-port USB-C controllers are fully programmable and can be easily customized for specific requirements.
The USB Type-C charger schematic designs and USB charger adapter circuit diagrams feature Infineon’s comprehensive portfolio of silicon and gallium nitride based high- and low-voltage power switches, USB-PD power and protocol controllers, USB-C cable marker controllers as well as ESD protection devices.
Our reference designs allow for the quick and easy development of prototypes, meaning manufacturers can benefit from new, fast-charging adapter technology while reducing development costs and time to market. Thanks to decades of experience in the electronics industry, Infineon drives the trend of adapter miniaturization without compromising on product efficiency and performance.
