ISL6566CRZAR5184

Special Purpose Regulators Overview

The ISL6566CRZAR5184 is a three-phase PWM controller IC designed for advanced microprocessor voltage regulation. It integrates power MOSFET drivers and supports Intel VRM9, VRM10, and AMD Hammer applications. The device operates with an input voltage range of 3V to 12V and provides a single output adjustable from 0.8V to 1.6V. It is housed in a 40-VFQFN (6x6) package with exposed pad, suitable for surface mount installation. The component functions within an operating temperature range of 0°C to 70°C.

Special Purpose Regulators Feature Summary

• Integrates three-phase PWM control logic with dedicated power MOSFET gate drivers to simplify power stage design.
• Provides precision voltage regulation specifically optimized for high-performance CPU core power delivery.
• Supports standard protocols for Intel VRM9, VRM10, and AMD Hammer processor architectures.

Special Purpose Regulators Applications

• Intel VRM9 compliant motherboard designs
• Intel VRM10 compliant motherboard designs
• AMD Hammer architecture processor power supplies

Special Purpose Regulators Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the specific suffix AR5184 matches the required marking and packaging specifications for existing bill of materials. Check for available cross-reference or replacement options from Renesas due to end-of-life status. Ensure supply chain sources provide genuine parts with valid traceability documentation.

Special Purpose Regulators Selection Notes

Select this controller when designing for legacy Intel VRM9/VRM10 or AMD Hammer platforms requiring integrated three-phase buck control. Consider the 40-QFN package size constraints and thermal requirements for the exposed pad. Evaluate if newer Renesas controllers offer better efficiency or feature sets for modern processor generations.

Special Purpose Regulators Part Context

This part belongs to the ISL6566 series of three-phase PWM controllers manufactured by Renesas Electronics. It is distinct from single-output variants like the ISL6566CRZ by providing multi-phase control capabilities essential for high-current CPU cores. The series targets desktop and workstation motherboard power management solutions.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete product status, direct replacements may require architectural redesign or selection of alternative multi-phase controllers from current Renesas portfolios.
