IR3541MTYPBF Description

The IR3541MTYPBF is a dual-loop digital multi-phase buck controller that drives up to 5 phases. The IR3541MTYPBF is fully Intel? VR12 and AMD? SVI compliant on both loops and provides a Vtt tracking function for DDR memory. The IR3541MTYPBF includes the IR Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR Variable Gate Drive optimizes the MOSFET gate drive voltage as a function of real-time load current.
