Product details
Overview
ISL95829CHRTZ-T from Renesas Electronics is a 3-phase VR controller with two integrated gate drivers and SVID interface, compliant with Intel IMVP9 specifications for CPU core power delivery. It supports 1-/2-/3-phase configurations, DCR/resistor current sensing, remote voltage sense, and delivers 0.5% system accuracy over temperature in a 4×4 mm TQFN package.
For engineers reviewing the ISL95829CHRTZ-T datasheet, ISL95829CHRTZ-T pinout, ISL95829CHRTZ-T application, or ISL95829CHRTZ-T equivalent, key selection criteria include IMVP9 compliance, R3™ modulator transient response, PS4 low-power state support, programmable ICCMAX/slew rate, and compatibility with ISL95808 external drivers.
Technical Context
The ISL95829CHRTZ-T implements Renesas' Robust Ripple Regulator (R3™) topology, enabling variable switching frequency (up to 750 kHz), fast transient settling, and Diode Emulation mode for light-load efficiency. It uses SVID serial bus for dynamic voltage scaling and VR_READY signaling per IMVP9 protocol.
It supports dual current-sensing methods-lossless DCR sensing with single NTC thermistor compensation and precision resistor-based sensing-and includes differential remote sensing, programmable VBOOT, and PSYS input power monitoring via alternate VSYS mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VR controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95869HRTZ-T | Same die, identical R3™ architecture and pinout; differs only in temperature grade (−10°C to +100°C vs. −10°C to +85°C). | Targeted at extended-temperature industrial or ruggedized client platforms. | Select ISL95869HRTZ-T only if ambient operating temperature exceeds +85°C at the VR location. |
| RTQ2132B-QA | 3-phase controller with I²C interface (not SVID); no PS4 support; fixed 600 kHz switching frequency. | Designed for non-Intel platforms (e.g., AMD or custom SoCs) without IMVP9 protocol requirements. | Choose RTQ2132B-QA only for non-SVID systems where SVID command set and PS4 compliance are not required. |
Compared with ISL95829CHRTZ-T, ISL95869HRTZ-T offers identical functionality with extended thermal rating, while RTQ2132B-QA provides a non-SVID alternative lacking IMVP9-specific features like VR_READY sequencing and PSYS monitoring.

FAQ
What is the primary function of the ISL95829CHRTZ-T?
The ISL95829CHRTZ-T is a 3-phase voltage regulator controller designed to deliver tightly regulated core power to Intel IMVP9-compliant CPUs. It integrates two gate drivers, supports SVID communication, and implements R3™ modulation for fast transient response and high light-load efficiency. Its role is central to the CPU VRM, managing voltage scaling, current sensing, and power-state transitions in notebooks, desktops, and Ultrabooks.
Does the ISL95829CHRTZ-T support Intel's PS4 low-power state?
Yes, the ISL95829CHRTZ-T meets Intel IMVP9 PS4 specification requirements with low quiescent supply current during deep-sleep states. This enables platform-level power savings in modern client systems by reducing VRM standby consumption without compromising wake-up latency or regulation stability. The PS4 compliance is verified per Renesas' characterization data and is integral to the ISL95829CHRTZ-T's system-level power management capability.
Can the ISL95829CHRTZ-T be used with external gate drivers?
Yes, the ISL95829CHRTZ-T supports external gate drivers such as the ISL95808 to expand phase count beyond two integrated outputs. Its PHASE2 output can drive an external driver, enabling full 3-phase operation with all phases actively controlled. This configuration maintains SVID synchronization and load-line regulation integrity across all three phases, making it suitable for high-current CPU applications requiring >60 A output.
What current sensing methods does the ISL95829CHRTZ-T support?
The ISL95829CHRTZ-T supports both lossless DCR current sensing using inductor DCR with single-NTC thermistor compensation and precision resistor-based current sensing. DCR mode eliminates sense-resistor power loss and board space; resistor mode provides higher absolute accuracy. Both methods feed into the same control loop and support programmable ICCMAX, OCP, and load-line calibration - enabling flexible, application-optimized current measurement without hardware redesign.
Is the ISL95829CHRTZ-T pin-compatible with other ISL958xx controllers?
Yes, the ISL95829CHRTZ-T shares identical pinout and package (4×4 mm TQFN-40) with ISL95869HRTZ-T and ISL95869CRTZ-T. All share the same SVID interface, PHASEx outputs, CSN/CSOUT, VSEN±, and VR_READY signals. Firmware and layout are interchangeable across this family; only temperature grade and minor characterization differences distinguish them - allowing drop-in replacement for qualification or thermal margin adjustment without PCB revision.
