Highest Efficiency With The New Generation DrBlade™ 2
Save up to 35% board space without RC network. Reduce design-in effort & extend component lifetime.
Remember the long evenings spent at work to optimize your voltage regulator solutions? Finally leaving you exhausted and your boss nevertheless still not happy? Those hard times are now over.
Infineon’s latest power stage DrBlade™ 2 combines 3 chips in one single package – a HS/LS halfbridge configuration with a driver IC optimized to achieve peak efficiency values of above 95%.
In addition to the all-in-one solution, you can save up to 35% board space by the integrated current sense feature – meaning there’s no need for an external RC element anymore. But that’s not the only benefit. The integrated temperature and current telemetry feature-set offers superior system robustness as well as highest reliability, leading to a prolonged lifetime and reduced design-in efforts on your side. A maximum output current capability of 60A allows the system to operate with fewer phases, which can still be evenly balanced using telemetry. In combination with Infineon’s 4th generation digital controller family, the phase current can also be easily monitored via the IMON pin.
High customer takeup has meant that the DrBlade™ family has become a strong pillar in Infineon’s power stage portfolio, with the next generation already waiting in the wings.
