March 23, 2015, Seoul - Infineon Technologies (Korea CEO Lee Seung-soo) has launched the OptiMOS™ 5 25V and 30V product families. These next-generation power MOSFETs are offered in standard discrete packages, a new type of power stage called Power Block, and integrated power stage DrMOS 5x5. Infineon provides a complete system solution for applications such as servers, clients, data communications, or telecommunications, including drivers and digital controllers.

Megatrends such as cloud computing, Internet of Things, and social media are demanding higher computing performance in modern society, which in turn rapidly increases energy consumption, leading to requirements for energy efficiency within the power conversion chain. The newly launched OptiMOS 25V and 30V product families provide a benchmark solution achieving approximately 1% efficiency improvement across the full load range compared to the previous generation and peak efficiency exceeding 95% in typical server voltage regulator designs. This improved performance is based on switching loss (Qswitch) reduced by 50% compared to the previous OptiMOS technology. Therefore, using the new OptiMOS 25V, a single 130W server CPU operating 365 days per year can save 26.3kWh of energy annually, and by operating an additional 50,000 servers in a server farm, an average annual savings of 1.3GWh can be achieved.

New Packaging Technology

The newly launched OptiMOS 25V and 30V product families feature new packaging technology that further reduces PCB space. This packaging technology has been applied to the Power Block product family and integrated power stage DrMOS 5x5, and by providing source-down low-side MOSFET, it improves thermal performance with thermal resistance reduced by 50% compared to standard package solutions such as SuperSO8.

Infineon's Power Block contains both low-side and high-side MOSFETs of a synchronous DC/DC converter in a 5.0 x 6.0mm² package outline lead-free SMD package. Using the Power Block, the design can be reduced by up to 85% by replacing two separate discrete packages such as SuperSO8 or SO-8. The small package outline and the interconnection of the two MOSFETs within the package minimize loop inductance and maximize system performance.

OptiMOS 5 25V is also used in the integrated power stage DrMOS 5x5 combining a driver and two MOSFETs, where the total area occupied on the PCB is 25mm². The driver and MOSFET integrated solution shortens design time and provides simple design-in. Additionally, a well-designed power stage increases system reliability and performance with temperature sensing of high accuracy +/-5°C (±10°C with external sensing).

Complete System Solution Provision

Richard Kuncic, Vice President and Head of Power Management and Multimarket Business at Infineon Technologies, said, "The OptiMOS 5 product family significantly reduces switching loss, enabling design operation at higher switching frequencies, reducing energy consumption, and lowering overall system costs. Infineon provides a broad and complete solution for DC/DC voltage regulation applications along with digital IC and driver product families, and especially the DrMOS 5x5 and Power Block products are the optimal choice for achieving maximum efficiency with industry-standard footprints."

Availability

OptiMOS 25V and 30V devices with on-resistance ranging from 0.9mΩ to 3.3mΩ are provided in SuperSO8, S3O8, and Power Block packages as samples. Products with monolithically integrated Schottky-like diodes and 30V products are scheduled for availability from the second quarter of 2015. DrMOS 5x5 is scheduled for launch in the second quarter of 2015, and samples are being provided. More details are available at the following sites.
