IR3541MGB03TRP Description
The IR3541MGB03TRP is a dual-loop digital multi-phase buck controller that drives up to 5 phases. The IR3541MGB03TRP is fully Intel? VR12 and AMD? SVI compliant on both loops and provides a Vtt tracking function for DDR memory. The IR3541MGB03TRP 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. IR Dynamic Phase Control adds/drops active phases based upon load current. The IR3541MGB03TRP can be configured to enter 1-phase operation and active diode emulation mode automatically or by command.
