ISL6334ACRZ-TK

Special Purpose Regulators Overview

The ISL6334ACRZ-TK is a 4-phase PWM controller designed for Intel VR11.1 microprocessor core voltage regulation. It operates with an input voltage range of 3 V to 12 V and provides an adjustable output voltage from 0.5 V to 1.6 V. The device utilizes a 40-VFQFN package with exposed pads, suitable for surface mount installation. It functions within a commercial temperature range of 0°C to 70°C.

Special Purpose Regulators Feature Summary

• Complies with Intel VR11.1 specifications for accurate load current reporting via the IMON pin.
• Employs Active Pulse Positioning (APP) and Adaptive Phase Alignment (APA) modulation schemes.
• Supports active phase adding and dropping to maintain high efficiency at light loads.

Special Purpose Regulators Applications

• Microprocessor core voltage regulation
• Intel VR11.1 compliant power systems

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors or verified supply chain channels. Confirm that the specific suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with existing PCB layouts regarding the 40-QFN footprint and thermal pad requirements before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component for applications requiring strict adherence to Intel VR11.1 standards. Consider its multiphase architecture for reducing input and output ripple currents compared to single-phase solutions. Evaluate thermal management needs due to the QFN package design and ensure the control loop supports the specified transient response requirements.
