O2Micro International Ltd launches the OZ8296 dual DC/DC converter controller for notebooks, ultrabooks and netbooks. It has two single phase controllers with integrated drivers for the CPU core and graphics rails, with both output voltages programmable through a high speed serial bus. The device is compliant with Intel's IMVP7/VR12 specification.

Based on Constant-Ripple-Current (CRC) technology, the converter controller integrates drivers for the CPU and GFX power supplies, achieving 94 per cent power conversion efficiency and limiting power loss in the system.

The OZ8296 is available in a 32-pin QFN package. Already in high volume production, samples and evaluation boards are available for qualified customers.
