IRU3007CW

Special Purpose Regulators Overview

The IRU3007CW is a synchronous buck controller designed for Intel Pentium II processor voltage regulation modules. It integrates four output channels to manage core, I/O, and auxiliary power rails. The device operates with input voltages of 5V and 12V. Packaged in a 28-pin SOIC format, it supports multi-phase configurations for high-current delivery. This component is classified as obsolete within the manufacturer's portfolio.

Special Purpose Regulators Feature Summary

• Integrated four-output architecture for simultaneous multi-rail generation
• Synchronous rectification control optimized for Intel Pentium II VRM standards
• Dual input voltage compatibility supporting 5V and 12V supply rails

Special Purpose Regulators Applications

• Intel Pentium II processor voltage regulation modules
• Multi-phase CPU power supply designs
• Legacy server motherboard power distribution units

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers due to obsolete status. Confirm package integrity and pin alignment before integration. Cross-reference datasheet revisions to ensure compatibility with legacy system requirements. Validate electrical parameters against original specifications prior to deployment in sensitive applications.

Special Purpose Regulators Selection Notes

Select this component only for maintenance of existing Intel Pentium II-based systems requiring exact functional replacement. Evaluate alternative modern controllers if designing new hardware, as current availability is limited. Ensure thermal management solutions align with the 28-SOIC package constraints. Verify that input voltage ranges match the target 5V and 12V rails without modification.

Special Purpose Regulators Part Context

This part belongs to Infineon Technologies' legacy PMIC lineup, formerly under International Rectifier. It was engineered specifically for the transition era of x86 processors requiring complex multi-voltage sequencing. The 28-SOIC package provides a compact footprint suitable for dense motherboard layouts typical of late 1990s computing platforms.

Special Purpose Regulators Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers must evaluate generic synchronous buck controllers with equivalent pinouts or utilize adapter boards for modern replacements.
