ISL6566CRZ-TR5184

Special Purpose Regulators Overview

The ISL6566CRZ-TR5184 is a three-phase PWM control IC designed for precision voltage regulation of advanced microprocessors. It integrates power MOSFET drivers to reduce external component count. The device supports Intel VRM9, VRM10, and AMD Hammer applications via VID inputs. It features differential remote sensing with ±0.5% system accuracy over temperature. Operation includes loss-less rDS(ON) current sampling for channel sharing and DCR sampling for load line programming. The controller offers selectable operation frequencies up to 1.5MHz per phase and variable gate drive bias ranging from 5V to 12V.

Special Purpose Regulators Feature Summary

• Integrates multi-phase power conversion capabilities supporting one, two, or three-phase operation within a single controller IC.
• Provides precision core voltage regulation through differential remote voltage sensing and adjustable reference-voltage offset.
• Utilizes loss-less rDS(ON) current sampling for precise channel current sharing and loss-less inductor DCR current sampling for accurate load line programming.
• Supports dynamic VID technology with selectable compatibility for Intel VRM9, VRM10, and AMD Hammer DAC codes.

Special Purpose Regulators Applications

• Intel VRM9 compliant CPU voltage regulator modules
• Intel VRM10 compliant processor power systems
• AMD Hammer architecture motherboard power supplies

Special Purpose Regulators Procurement Notes

Verify the specific suffix TR5184 against official Intersil or Renesas documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements if lead-free status is required for your assembly process. Cross-reference the manufacturer part number with current Renesas Electronics America listings to confirm availability and datasheet version integrity before procurement.

Special Purpose Regulators Selection Notes

Select this component when designing multi-phase buck converters for high-performance processors requiring integrated driver functionality. It is suitable for designs needing precise current sharing without external sense resistors. Consider its compatibility with specific VID protocols if interfacing directly with Intel or AMD processors. Evaluate the thermal performance of the QFN package relative to the total power dissipation of the integrated drivers and control circuitry.

Special Purpose Regulators Part Context

This part belongs to the ISL6566 family of three-phase PWM controllers manufactured by Intersil, now part of Renesas Electronics. The series is characterized by the integration of MOSFET drivers to simplify power stage design. The CRZ suffix typically indicates commercial temperature grade and Pb-Free plus Anneal construction. The TR5184 designation specifies the reel quantity and packaging format for automated assembly.

Special Purpose Regulators Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Generic multiphase controllers may lack the specific VID protocol support or integrated driver characteristics required for direct replacement in VRM9/VRM10 designs.
