Abstract
A circuit for use with a Universal Serial Bus (USB) socket includes a power converter coupled to receive an input voltage at an input terminal and coupled to provide an output voltage at an output terminal. A transistor is coupled between the output terminal of the power converter and a bus voltage terminal of the USB socket. A USB communication controller is coupled to the USB socket. The USB communication controller includes an output terminal coupled to a control terminal of the transistor. A bleeder circuit is coupled between the output terminal of the USB communication controller and the bus voltage terminal of the USB socket.
