While both Android and Hongmeng are using USB-C as a charging port, Apple's ipads and MacBooks are also using USB-C as a charging port. Expect Apple to add the iPhone charging port to USB-C as well.
If the iPhone's charging port is changed to USB-C, it will greatly expand the USB-C family of devices, and leverage the influence of Apple's iPhone brand to bring more USB-C-compatible devices, such as power tools, game consoles or notebook power supplies for games. Can reduce the use of wire so, raise environmental protection sex.
At the same time, by USB-C PD3.1 protocol specification, the charging speed of iPhone can be greatly improved, and the same fast charging experience as Android phone can be achieved, which can greatly improve the user experience of Apple users.
Apple was the first company to release and mass-produce a USB PD3.1 140W charger. The three-level topology of single-phase PFC+ZVS BUCK+ open-loop LLC is used. The 140W charger of PD3.1 leads the trend, allowing more charger manufacturers to develop 140W chargers of different sizes.
Apple is a great company. When designing the PD3.1 140W charger, Apple has also considered the feasibility of the topology of PD3.1 240W. The three-level topology used by Apple can achieve the full range of output of 5V to 48V USB PD3.1. However, the existing flyback topology cannot achieve such a wide output voltage due to various deformations.
It is believed that Apple's unified use of USB-C port will push USB-C port from the current mainstream 140W to more powerful 240W applications.
