Renesas plans to release the first discrete controllers with USB 3.0 specifications support USB Power Delivery. These extensions specifications USB 3.0 and USB 2.0, recall will allow transfer to USB-cable power up to 100 W (20 V, 5 A).
USB Power Delivery specification published in July 2012 . However, apart from a modest demonstration at CES 2013 on the practical implementation of extensions USB Power Delivery nothing was heard until yesterday. As it turned out, the first broad demonstration of capabilities powered by a powerful peripherals USB-cable held a few days ago in Japan on a thematic exhibition Embedded Technology 2013.
Note, the company demonstrated a bench model controller using FPGA-matrices. Commercial single-hull version of the USB controller with support for USB Power Delivery will be in the period from April to October 2014. In finished products, thus, support for USB power will be realized only in winter of next year. Renesas plans to support only two: 18 W (5 V, 3 A) and 36 W (12 V, 3 A). In the first case we can talk about charging the tablet via USB, the second - thin laptops and charging systems two in one (convertible notebooks). Other profiles - 10 W, 60 W and 100 W - will be supported by the controllers on the next development stages .
For operation of the USB Power Delivery need new cables and new connectors. But the overall constructive USB will be saved .
Yesterday responsible for the standard of the organization issued a press release in which it announced the preparation of a new USB-connector - Type-C. Specification with its description will be taken in the middle of next year. New connector in some way is a carbon copy of the connector Apple Lightning. It is further noted that the new socket is created with a margin as scalability for transmitting power to the peripheral device (USB Power Delivery), and taking into account the future growth speed of transmission interface (since version USB 3.1 and higher).
