OZ8321 and OZ8322 DC/DC Controllers Extend Battery Life, Improve Efficiency and Are Compliant With AMD’s SVI2 Specification for Notebook Computer Applications

O2Micro(R) International Limited OIIM +2.30% , a global leader in the design, development and marketing of high-performance integrated circuits and solutions, today announced the introduction of two new low cost, high efficiency Direct Current-to-Direct Current (DC/DC) converter controllers for notebook markets.

The expanding feature sets and performance requirements of today’s notebook 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 proportionally.

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 notebooks by improving efficiency and enhancing overall CPU performance.

Laszlo Lipcsei, vice president of O2Micro, said, “O2Micro continues to develop circuits and components that improve the efficiency and performance of next generation notebook computing. Our new CPU DC/DC controllers, based on O2Micro’s Constant-Ripple-Current(R) Technology, are compliant with AMD’s SVI2 specification for its latest “A” series, second generation Accelerated Processor Units (APUs) and are optimized for superior performance.”

About the OZ8321 and OZ8322 DC/DC Controllers

The OZ8321 is a highly integrated DC/DC controller containing a dual phase controller with integrated drivers for the core rail and a single phase controller for the North Bridge (NB) rail. Both output voltages are programmed through a high speed serial bus, compliant with the SVI2 specification.

The OZ8322 is a highly integrated DC/DC controller containing a dual phase controller with integrated drivers for the AMD CPU core rail and a dual phase controller with external drivers for the North Bridge rail (companion chip:OZ8002). Both output voltages are programmed through a high speed serial bus, compliant with the SVI2 specification.

Product Availability and Additional Information

The OZ8321 and OZ8322 are available in a 40-pin QFN package. Both products are in high volume production. Samples and evaluation boards are available for qualified customers.
