ISL6263DHRZ

Special Purpose Regulators Overview

The ISL6263DHRZ is a single-phase synchronous buck PWM voltage regulator designed for Intel IMVP-6 GPU core power applications. It features Robust Ripple Regulator (R3) technology and integrates a current monitor. The device operates with an input voltage range of 5V to 25V and supports switching frequencies from 200kHz to 500kHz. It provides a programmable output voltage range of 0.41V to 1.29V, delivering up to 25A of output current. The component is housed in a 32-lead TQFN package measuring 5mm x 5mm.

Special Purpose Regulators Feature Summary

• Integrates Robust Ripple Regulator (R3) technology for enhanced transient response
• Includes built-in current monitoring capability for system protection
• Complies with Intel IMVP-6 specification for smart voltage regulation

Special Purpose Regulators Applications

• GPU core power supply for Intel Santa Rosa platform
• Single-phase DC/DC buck conversion for low-power CPU/GPU cores
• Embedded systems requiring IMVP-6 compliant voltage regulation

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'DHRZ' against official Renesas or Intersil documentation to confirm the exact pinout and thermal pad configuration. Ensure compatibility with IMVP-6 control signals. Check for End-of-Life (EOL) status or obsolescence notices, as this component series may have been discontinued or replaced by newer generations. Confirm moisture sensitivity level handling requirements during assembly.

Special Purpose Regulators Selection Notes

Select this component when a single-phase solution is sufficient for the target load current and transient requirements. Verify that the 25A output capability aligns with the peak demand of the GPU core. Ensure the design supports the required 5-bit VID interface for voltage selection. Consider the 32-QFN package size constraints and thermal dissipation needs for the operating environment.

Special Purpose Regulators Part Context

The ISL6263DHRZ belongs to the ISL6263 family of single-phase voltage regulators developed by Intersil, now part of Renesas Electronics. This family targets mobile and embedded processors requiring efficient power management. The 'D' variant specifically denotes the inclusion of integrated current monitoring, distinguishing it from other variants in the series that may lack this feature or differ in VID bit resolution.
