DrBlade 2 Power Stage and Fourth-Generation Digital Controller

Infineon DrBlade 2

Infineon's digital voltage regulation solution combining a DrBlade™ 2 power stage and a Magni4 controller provides maximum configuration flexibility with a minimum external component count. This solution was designed to meet the increasingly stringent voltage regulation requirements of new microprocessor generations, memory systems and SoC power applications. Small, extremely 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% for maximum system performance.
