Abstract
A transitional USB receptacle has one USB PD port and one USB-C port (non-PD). The receptacle includes flyback topology for AC/DC conversion, a bypass circuit, a buck converter, and a USB controller that determines the voltage demands of external devices connected to the USB-C and PD ports. The flyback topology uses a transformer with two sets of windings that produce different output voltages. The bypass switch is configured to ensure that only voltage signals under 10V are input to the buck converter, resulting in a different one of the transformer output voltages being input to the buck converter under different load demands. This enables the buck converter to more efficiently produce a 5V at the USB-C port when the USB PD port needs to simultaneously supply either 15V or 20V, and also enables the buck converter to more efficiently produce a 5V or 9V output at the USB PD port.
