Low-power USB 3.0 hub controller suits next-gen Ultrabook designs
VIA Labs, Inc. announced its 3rd generation USB 3.0 hub controller, the VIA Labs VL812. The controller uses a new low-power design and features an integrated 5V DC-DC switching regulator, offering a single-chip solution that achieves both high power efficiency and greater system integration. In typical configurations, the unit consumes <0.5 W under load, allowing users to attach an external 2.5" USB 3.0 hard drive, USB 2.0 Flash drive, and a USB Mouse simultaneously without the need for an AC adapter, when connected to a regular USB 3.0 port, according to the company. The VIA Labs VL812 four-port USB 3.0 hub controller supports the higher transfer rates of the USB 3.0 specification, while remaining fully backwards compatible with USB 2.0 and 1.1 hosts, hubs, and devices. In addition to rapid transfers, the device integrates battery charging controller logic, enabling Dedicated Charging Port (DCP) and Charging Downstream Port (CDP) functionality as described in the USB Battery Charging 1.2 specification, in addition to supporting the YD/T 1591-2009 specification and other vendor-specific modes.
