ISL6263BHRZ

Special Purpose Regulators Overview

The ISL6263BHRZ is a single-output, non-isolated DC/DC buck converter manufactured by Renesas Electronics Corporation. It belongs to the Robust Ripple Regulator (R3) series and is designed for Intel IMVP-6 applications. The device operates with an input voltage range of 5V to 25V and provides an adjustable output voltage between 0.41V and 1.29V. It features a switching frequency range of 200 kHz to 500 kHz and is housed in a 32-pin QFN package.

Special Purpose Regulators Feature Summary

• Implements Robust Ripple Regulator (R3) topology for enhanced transient response
• Configured specifically for Intel IMVP-6 processor power requirements
• Supports wide input voltage ranges suitable for various system architectures

Special Purpose Regulators Applications

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm RoHS3 compliance status and check for available tape-and-reel alternatives if standard packaging is unavailable. Review recent Product Change Notices for any manufacturing or labeling updates that may affect integration.

Special Purpose Regulators Selection Notes

Select this component for legacy Intel IMVP-6 compatible designs requiring a single-phase buck solution. Ensure the application supports the specified 200 kHz to 500 kHz switching frequency range. Verify that the 32-QFN package dimensions fit the target PCB layout constraints and thermal requirements.

Special Purpose Regulators Part Context

This IC is part of the broader ISL6263 family from Renesas, which includes variants like the ISL6263A and ISL6263AIRZ. These components share the R3 technology platform but may differ in pinout, packaging, or specific electrical characteristics tailored for different processor generations or form factors.

Special Purpose Regulators Replacement Considerations

Check for direct substitutes within the ISL6263 family, such as ISL6263AIRZ, noting potential differences in package type or revision status. Evaluate newer Renesas PMICs for modern processor platforms if upgrading design architecture.
