ISL6334DCRZ-T

Special Purpose Regulators Overview

The ISL6334DCRZ-T is a four-phase PWM controller designed for microprocessor core voltage regulation. It operates within an input voltage range of 3V to 12V and provides a single output with adjustable voltage from 0.5V to 1.6V. The device supports up to 200A output current capability and functions at a switching frequency of 1MHz. It is housed in a 40-VFQFN exposed pad package and complies with Intel VR11.1 specifications.

Special Purpose Regulators Feature Summary

• Implements proprietary Active Pulse Positioning (APP) and Adaptive Phase Alignment (APA) modulation schemes for fast transient response.
• Utilizes active phase adding and dropping mechanisms to maintain high efficiency across light to full load conditions.
• Features accurate load current reporting via the IMON pin for direct microprocessor communication.

Special Purpose Regulators Applications

• Microprocessor core voltage regulation
• Intel VR11.1 compliant power designs
• High-performance server platforms

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm datasheet revisions and PCN documentation for assembly site changes. Validate RoHS compliance and moisture sensitivity levels prior to PCB assembly planning.

Special Purpose Regulators Selection Notes

Select this component for applications requiring strict adherence to Intel VR11.1 standards. Ensure thermal management aligns with the QFN-40 package constraints. Verify compatibility with target processor PSI# signaling requirements for optimal light-load operation.

Special Purpose Regulators Part Context

This part belongs to the ISL6334 series, which includes variants like ISL6334AIRZ and ISL6334ACRZ-TK. These controllers share similar multiphase architectures but differ in temperature ranges and packaging options. The series targets high-efficiency CPU power delivery systems.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available as the product is discontinued. Evaluate compatible next-generation Renesas VR controllers or consult manufacturer engineering support for migration strategies.
