ISL6334IRZ

Special Purpose Regulators Overview

The ISL6334IRZ is a VR11.1 compliant, four-phase PWM controller designed for Intel and AMD CPU power delivery applications. It operates within an input voltage range of 5V to 12V and supports output voltages from 0.38V to 1.6V. The device features a switching frequency of 1 MHz and supports load currents up to 200 A. It is housed in a 40-lead QFN package with exposed pad and functions reliably across an industrial temperature range of -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Complies with Intel VR11.1 specifications for advanced processor power management
• Integrates phase dropping and droop disabled modes for optimized efficiency
• Includes built-in load current monitoring capabilities for system protection

Special Purpose Regulators Applications

• Intel VR11 CPU core voltage regulation
• AMD CPU power supply design
• High-performance server motherboard power stages

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors due to discontinuation status. Confirm RoHS compliance and moisture sensitivity level before assembly. Check for specific manufacturing site changes or alternate bond wire materials documented in Product Change Notices. Ensure ECAD models match the final revision used in design.

Special Purpose Regulators Selection Notes

Select this model for designs requiring strict adherence to VR11.1 standards with industrial temperature ratings. Compare against ISL6334DIRZ if commercial temperature range suffices. Evaluate pin compatibility with existing layouts when transitioning from previous generations. Consider the 40-QFN footprint constraints during PCB layout planning.

Special Purpose Regulators Part Context

Part of the ISL6334A series, which includes variants like ISL6334AIRZ and ISL6334CRZ. These controllers share the same core architecture but differ in temperature grades and packaging options. The series targets high-current multi-phase buck converter applications for modern processors.
