Alpha and Omega Semiconductor Limited Forms Joint Venture with State Authority of Chongqing for New Power Semiconductor Manufacturing Facility in the Liangjiang New Area of Chongqing

Alpha and Omega Semiconductor Limited announced that it has entered into a preliminary agreement with the state authority of Chongqing, China, to form a joint venture for a new power semiconductor manufacturing facility in the Liangjiang New Area of Chongqing. Under the proposed agreement, the initial capitalization of the joint venture is expected to be approximately $300 million. The Chongqing authority would own 49% of the venture's equity and invest in cash. AOS would own 51% of the equity and contribute primarily its existing assembly and testing equipment as well as certain intellectual property related to the operation of the facility. The joint venture is expected to begin manufacturing operations in 2017. AOS will gradually move its assembly and testing equipment from the company's existing facility in Shanghai to the lower-cost Chongqing region. At a later date, the joint venture expects to construct a 12-inch fabrication facility that is suited for the production of power semiconductors. The parties are negotiating a definitive joint venture agreement setting in more detail the financial and business terms, as well as the timeline, of the proposed project, which is expected to be a multi-year commitment divided into several stages. The execution of the joint venture agreement will be subject to various conditions, including the relevant government agency review and approval.

Alpha & Omega Semiconductor, Ltd. to Propose Amendment of Bye-Laws

Alpha and Omega Semiconductor Releases AOZ3053, A Smart EZBuck(TM) Regulator Featuring Adaptable Light Load With Surge Output Current Capability

Alpha and Omega Semiconductor Limited announced the release of the AOZ3053, a 5A EZBuck DC/DC regulator with smart mode adaption functions, available in a thermally enhanced exposed pad SO-8 package. The AOZ3053 is the first of this new smart platform, which allows for more thermally efficient DC/DC solutions for consumer, networking and industrial applications such as LCD TVs, set-top boxes, cable modems, and power supplies. The AOZ3053 is a high efficiency and simple-to-use synchronous step-down regulator with PWM switching frequency of 500kHz and input voltage range of 4.5V to 18V. Leveraging AOS's co-package EZBuck design, the AOZ3053 integrates a 55mW high-side and 15mW low-side MOSFET, and provides 5A of continuous output current at over 90% efficiency and maintains it at 85% efficiency while in 10mA light load operation. This new device offers various features such as adaptable light load with surge output current capability, over-voltage protection, cycle-by-cycle current limit and short-circuit protection which are a must when powering high-end digital ICs.
