Abstract

A conversion device is configured to include a first connection port that is a connection port of a USB Type C; a second connection port that is a connection port of a USB other than the USB Type C; a third connection port that is a connection port of a power supplying wire; a communication wire that is connected to a communication line between the first connection port and the second connection port; and a power wire that is connected to a power line between the first connection port and the third connection port.

Claims

1. A conversion device comprising:

a first connection port that is a connection port of a USB Type C;

a second connection port that is a connection port of a USB other than the USB Type C;

a third connection port that is a connection port of a power supplying wire;

a communication wire that is connected to a communication line between the first connection port and the second connection port; and

a power wire that is connected to a power line between the first connection port and the third connection port.

2. The conversion device according to claim 1,

wherein the power wire includes a power supply circuit that generates power which is supplied to a device that is connected to the third connection port, based on power that is supplied from a host which is connected to the first connection port.

3. The conversion device according to claim 2,

wherein the power supply circuit outputs profile data of power to the host through a wire that is connected to the first connection port.

4. The conversion device according to claim 3,

wherein the power supply circuit includes a voltage boosting/dropping circuit that generates power of a voltage which is stored corresponding to the profile data, based on power that is supplied from the host which is connected to the first connection port.

5. The conversion device according to claim 2,

wherein the power supply circuit includes a connection detecting circuit that detects whether or not a connector is connected to the third connection port, and starts supplying of power to the third connection port in a case where the connection detecting circuit detects that the connector is connected to the third connection port.

6. The conversion device according to claim 1,

wherein the communication wire includes a redriver circuit which shapes a waveform of a signal that is transmitted through the communication line.
