DC-DC Integrated Power Stage
Infineon offers a wide portfolio of power stages solutions, recognized in the whole industry as best-in-class for power efficiency and power density. Our product offering includes highest efficiency integrated power stages such as 25V latest generation power stages, DrMOS, DrMOS 5x5, and DrMOS 4x4 as well as MOSFET gate drivers tailored to our OptiMOS™ and Primarion products.
The latest integrated power stages combine the most advanced low voltage MOSFET technology with our latest driver design. Integrated into our multichip PQFN package, the technologies offer customers a best-in-class efficiency device for managing processor power. This integration of driver technology, FET technology and package technology also demonstrates the powerful combination of Infineon and International Rectifier’s capabilities. All integrated power stages in this new portfolio are available in industry standard 5x6 footprints and various current ratings, covering high-end and price performance customer requirements.
With the DrMOS, packaged in a very small 4.0x4.0x1.0mm³ PQFN envelope, best-in-class efficiency and very low power loss keep up innovation of the integrated power stage space. Matching the latest generation 25V OptiMOS™ 5 power MOSFET technologies with the MOSFET driver silicon provides these additional benefits. DrMOS allows outstanding efficiency at higher switching frequency thanks to a substantial reduction of switching. The small package and high switching frequency helps designers to save board space and still deliver superior performance.
DrMOS 5x5 is an integrated power stage for high performance DC/DC Voltage Regulation solutions, comprising Infineon’s Driver and OptiMOS™ 5 25 V MOSFET technologies in a 5.0x5.0x0.8mm3 package. Together with Infineon’s digital VR controller, DrMOS 5x5 offers best-in-class efficiency and power density, developed, qualified and validated as a system solution from Infineon. It is optimized for next generation voltage regulation standards in server applications, such as Intel’s VR platforms.
