System Solution for Datacom/Telecom

DC-DC Solution for FPGA, ASSP and ASIC in Datacom/Telecom

Infineon’s digital voltage regulation system solution combining 4th generation VR controller and DrBlade™ 2  power stage provides highest configurability with minimum external component count. It meets increasingly stringent voltage regulation requirements of next generation FPGA, ASSP and ASICs in today’s medium and high current PoL applications used in Telecom/Datacom environments.

The digital multi-phase and multi-rail controllers enables OEMs and ODMs to improve efficiency and total cost of ownership while increasing power density and optimizing the total system footprint of the voltage regulator.
