ISL6266AHRZ

Special Purpose Regulators Overview

The ISL6266AHRZ is a single-output synchronous step-down voltage converter controller from Renesas Electronics, part of the Robust Ripple Regulator (R3) series. Designed for Intel IMVP-6 processor power applications, it operates with an input voltage range of 5V to 25V and provides an adjustable output voltage between 0.3V and 1.5V. The device is housed in a 48-VFQFN package with exposed pad, measuring 7x7 mm. It supports surface-mount installation and functions within a junction temperature range of -40°C to 100°C.

Special Purpose Regulators Feature Summary

• Implements the Robust Ripple Regulator (R3) control architecture for enhanced transient response and stability.

Special Purpose Regulators Applications

• Intel IMVP-6 CPU core voltage regulation

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly. Cross-reference datasheet revisions and PCN documents for any manufacturing site or material changes prior to integration into production designs.

Special Purpose Regulators Selection Notes

Select this controller specifically for legacy Intel IMVP-6 platform designs requiring a single-phase solution. Evaluate thermal performance within the 48-QFN package constraints against system current demands. Ensure compatibility with existing gate drive requirements and external MOSFET selection for the target voltage and current specifications.

Special Purpose Regulators Part Context

This component belongs to the ISL6266 family of power management ICs tailored for high-performance computing processors. It serves as a dedicated voltage regulator module (VRM) controller, distinct from multi-phase or general-purpose DC-DC controllers found in other Renesas product lines.
