Renesas collaborates with Diodes Inc to Accelerate promotion of USB Power Delivery

May 29, 2014 by Jeff Shepard

Renesas Electronics Corporation today announced its collaboration with Diodes Incorporated to deliver optimized charging solutions for USB Power Delivery (PD). Based on a Renesas USB Power Delivery Controller (PDC) and Diodes multi-mode active rectifier (AR), the companies' reference design provides turnkey solutions for AC adapters and PD-capable chargers compliant with the USB PD open standard. The AC adapter solution will be exhibited at the Computex Taipei from June 3 to June 7, 2014 at booth # N0608, 4th floor of the Nangang exhibition hall in Taipei. The solution to be showcased at Computex will provide ODMs and OEMs with a fast-to-market vehicle for mobile solutions and is expected to be deployed in 2015.

Charging mobile phones through USB connections has become the norm and demand for higher power charging has increased exponentially due to the mass adoption of tablets and ultrabook computers. In July 2012, the USB Implementers Forum (USB-IF) released the USB Power Delivery Specification to enhance power supply capability through USB cables up to 100W, providing a common standard for faster and safer charging of mobile devices.

Renesas has been a strong promoter of USB-IF since 1996. The company not only provides many USB silicon devices, but also dedicates its USB expertise to successfully launching “building block” solutions for numerous USB standards. Today, there are billions of USB devices in the world and the USB PD technology is anticipated to be an open industry standard that addresses the future charging needs and additional interface features required for next-generation mobile computing.

“We are pleased to work with Renesas to provide the industry with turnkey USB PD solutions. In addition to the PD-capable charger and AC adapter solution, Diodes will continue to develop discrete and analog products to enable other USB PD platforms,” said Francis Tang, Vice President, Worldwide Discrete Products, Diodes Incorporated. “By combining both companies' innovation and expertise, we will be able to realize USB Power Delivery in various applications and further expand new markets for USB charging.”

“We are pleased to share our USB Power Delivery controller expertise with Diodes for the development of turnkey solutions that help reduce time-to-market and power consumption, while offering the best-in-class cost performance,” said Terukazu Watanabe, Associate Chief of OA & ICT Business Division, Renesas Electronics Corporation. “Starting with AC adapter solutions, Diodes and Renesas will continue to work together as the industry leaders to expand USB Power Delivery offerings with the highest quality and significantly stable and safe charging systems that provide high value to our customers in consumer and portable electronics.”

As a member of the USB Implementers Forum (USB-IF) since 1996, Renesas (formerly NEC Electronics) has played a leading role both in defining USB standards and developing USB technology. In April 2000, the company (then NEC Electronics) launched the world's first USB 2.0-compliant host controller chip (uPD720100), the world's first USB 2.0-compliant hub controller chip (uPD720110) and an extensive lineup of other USB devices. Renesas has earned a reputation for delivering dedicated customer service and high quality. In May 2009, Renesas (then NEC Electronics) introduced the industry's first USB 3.0 xHCI host controller (uPD720200) and earned the first “Certified SuperSpeed USB (USB 3.0)” certification from the USB-IF. With the robust and compliant design of uPD720200, Renesas contributed to the USB-IF certification tests, providing the organization with the host controller products as the platform for other USB 3.0 peripheral device certification.
