ISL6561IRZR5284

Special Purpose Regulators Overview

The ISL6561IRZR5284 is a specialized voltage regulator controller IC manufactured by Renesas Electronics Corporation. Designed for Intel VR10X applications, it features four independent output channels with an adjustable output voltage range of 0.84V to 1.6V. The device operates from a single input supply between 3V and 12V and is housed in a 40-VFQFN package with exposed pad dimensions of 6x6 mm. It supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Special Purpose Regulators Feature Summary

• Supports multi-phase power delivery architectures compliant with Intel VR10X specifications
• Integrates control logic for four distinct output channels
• Features adjustable output voltage regulation capabilities

Special Purpose Regulators Applications

• Intel VR10X voltage regulator modules
• Multi-phase CPU core power supplies
• Server and workstation motherboard power stages

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status as the base ISL6561 series may have non-compliant variants. Ensure the specific suffix R5284 matches design requirements. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring Intel VR10X compliance with four-phase power distribution. Compare against single-phase alternatives like the ISL6566 if fewer outputs are sufficient. Verify thermal management needs for the 40-QFN package. Ensure input voltage ranges align with system bus voltages between 3V and 12V.

Special Purpose Regulators Part Context

This part belongs to the ISL6561 family of voltage regulator controllers. It shares functional similarities with other Intel VRM-compatible devices but offers specific channel counts and pinouts tailored for high-performance computing platforms. The R5284 suffix indicates a specific tape-and-reel packaging configuration.
