System Solution Digital VR Controller and DrBlade™ 2 Power Stage 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. The I2C/PMBus interface connects the digital controllers to the application system and provides real time telemetry information, monitoring and control capabilities. Small, highly efficient and thermally enhanced power stages in the novel RoHS 2016 compliant Blade packaging technology maximize power density and save PCB real estate. Continuous innovation in FET, driver and controller technology enable peak efficiencies above 95% to maximize system performance. The extensively validated system approach offers comprehensive telemetry, sense and protection features for superior system robustness as well as higher reliability and comes with the PowerCode™ Graphic User Interface (GUI) to program controller parameters and tune the VR while in operation. Furthermore Infineon has a highly trained worldwide engineering structure to provide high quality support from design to manufacturing.
