IR3505ZMTRPBF

Power Management - Specialized Overview

The IR3505ZMTRPBF is an XPhase3™ phase IC manufactured by Infineon Technologies, formerly International Rectifier. It serves as a specialized PMIC for processor power management applications. The device operates with a supply voltage range of 8V to 16V and draws a supply current of 3mA. It is housed in a 16-MLPQ (3x3) surface-mount package with exposed pad. The component is designed for high-frequency operation and integrates control logic for efficient power delivery.

Power Management - Specialized Feature Summary

• Integrates XPhase3™ technology for advanced phase control
• Optimized for processor power management applications
• Compact surface-mount packaging for space-constrained designs

Power Management - Specialized Applications

• Processor core voltage regulation
• Multi-phase power delivery systems
• High-density server power supplies

Power Management - Specialized Procurement Notes

Verify the manufacturer designation carefully, as the part was originally from International Rectifier but is now produced under Infineon Technologies. Confirm the exact suffix ZMTRPBF matches your bill of materials, as variations exist within the IR3505 family. Check the lifecycle status, as this specific variant may be marked obsolete or inactive in some distributor catalogs. Ensure compatibility with existing PCB footprints for the 16-MLPQ package.

Power Management - Specialized Selection Notes

Select this component when a dedicated phase controller for processor loads is required. Compare against other XPhase3 variants like the IR35217 if higher current or different pin counts are needed. Verify that the 8V-16V supply range aligns with your system's available rails. Consider the 16-MLPQ package constraints during layout planning to ensure adequate thermal dissipation and signal integrity.

Power Management - Specialized Part Context

The IR3505 series belongs to Infineon's XPhase3 portfolio, designed for high-performance computing. While International Rectifier was the original developer, Infineon acquired the brand and continues production. This specific part number represents a trimmed-down phase controller compared to full multi-phase controllers, often used in conjunction with gate drivers or integrated into larger PMIC solutions for CPU power stages.

Power Management - Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet indicates the product status as Obsolete or Inactive for certain suffixes. Engineers should consult official Infineon replacement guides or contact technical support directly for qualified alternatives.
