ISL6263CRZ

Special Purpose Regulators Overview

The ISL6263CRZ is a single-phase synchronous buck PWM voltage regulator designed for GPU core power applications. It utilizes Robust Ripple Regulator (R3) technology and supports Intel IMVP-6 specifications. The device features an integrated current monitor, differential remote sensing, and 5-bit VID input. It operates with an input voltage range of 5V to 25V and provides an adjustable output voltage from 0.41V to 1.29V. The controller supports a switching frequency range of 200kHz to 500kHz and delivers up to 25A output current. It is housed in a 32-lead QFN package.

Special Purpose Regulators Feature Summary

• Implements Intersil’s Robust Ripple Regulator (R3) Technology for enhanced transient response and stability.
• Includes an integrated current monitor for precise load regulation and protection.
• Supports differential remote sensing to minimize output voltage drop across PCB traces.

Special Purpose Regulators Applications

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Check for RoHS compliance documentation and moisture sensitivity level handling requirements. Confirm package marking codes against official datasheets to prevent counterfeit substitution. Review product change notifications for any packaging or material updates prior to procurement.

Special Purpose Regulators Selection Notes

Select this component for single-phase high-current applications requiring fast transient response. Ensure the design accommodates the 32-QFN thermal pad requirements for adequate heat dissipation. Verify compatibility with Intel IMVP-6 VID protocols if used in legacy platforms. Consider the limited availability and end-of-life status when planning long-term production runs.
