ISL95835HRZ-T

Special Purpose Regulators Overview

The ISL95835HRZ-T is a dual voltage regulator IC compliant with Intel IMVP-7 and VR12 standards, designed for microprocessor and graphics processor core power supplies. It integrates two regulators: the first configurable as a 3-phase or 2-phase VR, and the second as a 1-phase VR. The device utilizes Robust Ripple Regulator (R3) technology to provide fast transient response and variable switching frequency. It operates within an input voltage range of 4.5V to 5.5V and supports up to 30A output current per phase. The component is housed in a 40-pin QFN package.

Special Purpose Regulators Feature Summary

• Integrates a 3+1 phase controller architecture with three integrated gate drivers for direct MOSFET control.
• Implements Robust Ripple Regulator (R3) technology to achieve faster transient settling times compared to traditional PWM modulators.
• Supports lossless inductor DCR current sensing with single NTC temperature compensation or precise resistive sensing methods.
• Features independent programmable parameters for maximum current limits and thermal protection thresholds for both outputs.

Special Purpose Regulators Applications

• Intel IMVP-7 standard CPU core voltage regulation
• VR12 standard processor power delivery systems
• Graphics processor core power supply circuits

Special Purpose Regulators Procurement Notes
