O₂Micro Expands DC/DC Controller Family Supporting Notebook CPU Core and GFX Power Supplies

OZ8296 DC/DC Controller Features Integrated Drivers for CPU Core and GFX, Supports All Required Intel CPU IMVP7/VR12 Functions and Improves Efficiency

August 27, 2012. O₂Micro® International Limited (NASDAQ Global Select Market: OIIM), a global leader in the design, development and marketing of high-performance integrated circuits and solutions, today announced the introduction of a new low cost, high efficiency Direct Current-to-Direct Current (DC/DC) converter controller for notebook markets.

The OZ8296 dual DC/DC converter controller based on Constant-Ripple-Current^® (CRC) technology, features integrated drivers for CPU core and GFX power supplies, delivering up to 94% power conversion efficiency, significantly reducing overall power loss in the system.

"Leveraging our proprietary CRC technology and innovative packaging, the OZ8296 delivers increased efficiency with better performance over the entire load range," noted Laszlo Lipcsei, vice president of O₂Micro.

The expanding feature sets and performance requirements of today's ultrabook and netbook computers are driving demand for higher efficiency DC/DC controllers. With the integration of high speed CPU systems, the emphasis on current consumption and efficiency has increased substantially.

Unlike most stand-alone DC/DC controllers, O₂Micro's DC/DC controllers combine world-class expertise with a state-of-the-art, low noise design to enhance performance and optimize design integration. As a result, O₂Micro's DC/DC controllers enable greater functionality in next generation ultrabooks and netbooks by improving efficiency and enhancing overall CPU performance.

About the OZ8296 DC/DC Controllers

The OZ8296 is a highly integrated DC/DC controller containing two single phase controllers with integrated drivers for the CPU core and GFX rails. Both output voltages are programmable through a high speed serial bus and is compliant with Intel's IMVP7/VR12 specification.

Product Availability and Additional Information

The OZ8296 is available in a 32-pin QFN package. This product is in high volume production. Samples and evaluation boards are available now for qualified customers.
