IR3563BMMS07TRP

Special Purpose Regulators Overview

The IR3563BMMS07TRP is a specialized switching controller IC designed for Intel VR12 and VR12.5 voltage regulator architectures. It features a single output configuration housed in a compact 48-QFN (6x6) package with an exposed pad. The device operates with a 3.3V input supply and supports surface-mount installation. It functions within a temperature range of -40°C to 85°C ambient temperature. This component is classified under PMIC special purpose regulators and is currently marked as obsolete by the manufacturer.

Special Purpose Regulators Feature Summary

• Designed specifically for Intel VR12 and VR12.5 voltage regulator compliance
• Single-output control architecture integrated into a compact 48-pin QFN package

Special Purpose Regulators Applications

• Intel VR12 voltage regulator systems
• Intel VR12.5 voltage regulator systems
• Server and workstation power management modules

Special Purpose Regulators Procurement Notes

This component is officially discontinued and obsolete. Primary sourcing must rely on secondary distributors or surplus inventory providers. Verify lot dates and storage history carefully due to potential shelf-life degradation. Confirm RoHS compliance status through current datasheets, as environmental regulations may have evolved since production cessation. Ensure package integrity upon receipt.

Special Purpose Regulators Selection Notes

Select this part only if designing for legacy Intel VR12 or VR12.5 platforms requiring specific pinout compatibility. The 48-QFN package necessitates precise PCB thermal design considerations. Evaluate alternative modern controllers if new designs do not strictly require VR12/VR12.5 protocol adherence. Check availability constraints before finalizing schematics due to discontinuation status.

Special Purpose Regulators Part Context

The IR3563 series represents Infineon's dedicated solutions for high-performance CPU voltage regulation. The BMMS07 suffix indicates specific trim or versioning within the VR12/VR12.5 family. These controllers manage phase interleaving and transient response for processor cores. The 48-QFN form factor optimizes board space while providing necessary thermal dissipation paths through the exposed pad.

Special Purpose Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require functional equivalents from other manufacturers that support VR12/VR12.5 protocols. Consult official replacement guides for updated portfolio recommendations.
