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

O2Micro® International Ltd. 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.

According to the company, 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.

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.

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