IR3536A - International Rectifier

IR3536A Digital Multi-Phase Buck Controller

The IR3536A and IR3538A are dual-loop digital multi-phase buck controllers. The IR3536A drive up to 6 phases and the IR3538A drives up to 8 phases. The IR3536A and IR3538A are fully Intel® VR12 and AMD® SVI/PVI compliant on both loops and provide a Vtt tracking function for DDR memory. The IR3536A and IR3538A include the IR Efficiency Shaping Technology to d.
