UNIVERSAL SERIAL BUS HUB
First Claim
1. An universal serial bus (USB) hub, comprising:
- a power input port, configured to receive an input power;
a main power converting circuit, coupled between the power input port and a power bus, and configured to perform power conversion to the input power and output a main power to the power bus accordingly;
a first and a second type-C USB ports, respectively connected to a first and a second external electronic devices to perform data transmission or power transmission; and
a first and a second power converting circuits, respectively connected to the power bus to receive the main power, and respectively coupled to the first and the second type-C USB ports, wherein the first and the second power converting circuits respectively obtain a first and a second operation power information of the first and the second external electronic devices, and respectively generate and provide a first and a second operation powers required for normal operation of the first and the second external electronic devices according to the first and the second operation power information.

Abstract
An USB hub including a power input port, a main power converting circuit, a first and a second type-C USB ports, and a first and a second power converting circuits is provided. The power input port receives an input power. The main power converting circuit converts the input power into a main power. The first and the second power converting circuits receive the main power respectively, and are coupled to the first and the second type-C USB ports respectively. The first and the second power converting circuits respectively obtain a first and a second operation power information of a first and a second external electronic devices, and respectively generate and provide a first and a second operating powers required by the first and the second external electronic devices for normal operation according to the first and the second operation power information.
