Infineon Technologies AG introduced its integrated power stage family. With power efficiency rating reaching 96 percent, the new power stage devices can be combined with Infineon’s latest generation digital pwm power management controllers. This provides a full multiphase voltage regulation (VR) system solution for server, storage, client and communications systems. Infineon’s new integrated power stage family comes in 50A through 70A current ratings, and offers different efficiency levels to match design requirements.
The integrated power stage reduces power loss and simplifies design of VR solutions for multicore processors, ASICs and FPGA’s where efficient power management is critical. Maximum current rating of 70A in a small 5mm x 6mm PQFN SMD package supports phase reduction in multiphase systems. The integrated power stage family also offers smart self-protection with both over current and over-voltage protection, very accurate temperature and current information to the customer’s system.
Infineon’s dc-dc integrated power stage offering includes: The latest generation of high efficiency 25V integrated power stages; The new integrated power stages from Infineon combine the most advanced low-voltage MOSFET technology with the latest driver design. DrMOS 4×4 – Highest efficiency on smallest form factor; Infineon’s new DrMOS, packaged in a very small 4.0×4.0x1.0mm³ PQFN envelope, is offering best-in-class efficiency and very-low power loss. DrMOS 5×5 – Reach a peak efficiency of more than 95%; DrMOS 5×5 is an integrated power stage for high performance DC-DC Voltage Regulation solutions, comprising Infineon’s Driver and OptiMOS™ 5 25V MOSFET technologies in a 5.0×5.0x0.8mm 3 package.
DrBlade™ 2 – highest efficiency with The new generation ; The new DrBlade™ 2 maximizes power density and saves PCB real estate. Continuous innovation in FET, driver and controller technology enable peak efficiencies above 95% to maximize system performance. And DC-DC Voltage Regulation System Solution; Infineon’s digital voltage regulation complete system solution combining DrBlade™ 2 power stage and 4th Generation VR Controller provides highest configurability with minimum external component count to meet increasingly stringent voltage regulation requirements of new microprocessor generations.
“Infineon has greatly expanded its portfolio of power management technologies recently,” said Richard Kuncic, Vice President and General Manager of Infineon’s Business Line DCDC. “The integrated power stage combines further increases in energy efficiency with power density for enterprise power applications.”
