ISL6263ACRZ-T

Special Purpose Regulators Overview

The ISL6263ACRZ-T is a single-phase switching voltage regulator designed for Intel IMVP-6 Santa Rosa GPU core power applications. It operates with an input voltage range of 5 V to 25 V and delivers up to 25 A output current. The device features a programmable switching frequency between 200 kHz and 500 kHz, producing an adjustable output voltage from 0.412 V to 1.2875 V. Packaged in a 32-pin QFN (5x5 mm) with exposed pad, it supports pre-biased output start-up and includes integrated current monitoring capabilities.

Special Purpose Regulators Feature Summary

• Implements the Robust Ripple Regulator (R3) architecture for enhanced transient response and stability.
• Provides integrated current monitoring for precise load regulation and protection.
• Supports pre-biased output start-up to ensure safe initialization under existing bias conditions.

Special Purpose Regulators Applications

• Intel IMVP-6 Santa Rosa GPU core power supply
• Single-phase DC/DC buck converter designs

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm lot traceability and RoHS compliance status prior to integration. Check for recent Product Change Notifications regarding packaging or manufacturing site updates. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during reflow soldering.

Special Purpose Regulators Selection Notes

Select this component for applications requiring a single-phase solution compliant with Intel IMVP-6 specifications. Verify that the required output current does not exceed 25 A and that the input voltage remains within the 5 V to 25 V range. Consider the 32-QFN package constraints for thermal management and PCB layout. Evaluate the need for external components to set the switching frequency and output voltage accurately.

Special Purpose Regulators Part Context

This part belongs to the ISL6263A series of single-phase voltage regulators. It is specifically engineered for low-voltage, high-current applications such as GPU cores. The series utilizes advanced control techniques to minimize output capacitance while maintaining tight voltage regulation. It represents a specialized segment of Renesas's power management portfolio focused on mobile and desktop computing platforms.

Special Purpose Regulators Replacement Considerations

Check for direct pin-to-pin replacements within the ISL6263 family, such as the non-tape version ISL6263AIRZ. Verify compatibility with Intel IMVP-6 VID codes. Ensure any substitute maintains the same 32-QFN footprint and thermal characteristics. Confirm that alternative parts support the required 25 A current capability and operating temperature range.
