Product details
Overview
ISL95829CHRTZ from Renesas Electronics is a 3-phase VR controller with two integrated gate drivers and SVID interface compliance for Intel IMVP9 CPU power delivery, supporting 1–3-phase configurations, DCR/resistor current sensing, and remote voltage sensing in a 4×4 mm TQFN package.
For engineers reviewing the ISL95829CHRTZ datasheet, ISL95829CHRTZ pinout, ISL95829CHRTZ application, or ISL95829CHRTZ equivalent, key selection criteria include IMVP9 serial bus compatibility, R3™ modulator transient response, PS4 low-power state support, and programmable ICCMAX/slew rate for notebook/desktop VR design.
Technical Context
The ISL95829CHRTZ implements Renesas' Robust Ripple Regulator (R3™) topology to enable variable switching frequency during load transients and Diode Emulation mode for light-load efficiency. It uses SVID communication for dynamic voltage scaling and supports both lossless DCR and precision resistor-based current sensing.
This controller integrates adaptive body diode conduction time reduction and Acoustic Noise Reduction (ANR) via decay slew rate limiting. It delivers 0.5% system accuracy over temperature and meets Intel PS4 power requirements with low quiescent supply current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VR controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95869HRZZ | Same R3™ architecture and pinout; differs in thermal pad configuration (exposed pad vs. non-exposed) and minor biasing tolerances. | Targeted for higher-reliability industrial motherboard designs with enhanced thermal dissipation needs. | Select ISL95869HRWZZ only when board-level thermal modeling confirms need for improved junction-to-board conduction. |
| RTQ2132B-QA | Supports IMVP9 but lacks integrated gate drivers; requires external half-bridge drivers and adds 4–6 passive components. | Better suited for custom VR designs where layout flexibility and discrete driver tuning outweigh BOM simplification. | Choose RTQ2132B-QA only if design requires independent gate drive timing control or >750kHz switching frequency. |

FAQ
What is the primary function of the ISL95829CHRTZ in an Intel IMVP9 system?
The ISL95829CHRTZ serves as the main voltage regulator controller for Intel IMVP9 CPUs, managing dynamic voltage scaling, phase configuration (1–3-phase), current sensing, and power sequencing via the SVID interface. Its R3™ modulator ensures fast transient response and high accuracy, making it essential for stable CPU operation across varying workloads in the ISL95829CHRTZ-based VR design.
Does the ISL95829CHRTZ integrate gate drivers, and how many phases can it support?
Yes, the ISL95829CHRTZ integrates two high- and low-side gate drivers and supports configurable 1-, 2-, or 3-phase operation using those drivers plus one external driver. This architecture allows flexible power delivery scaling while minimizing external component count - a key advantage of the ISL95829CHRTZ in space-constrained mobile platforms.
What current sensing methods does the ISL95829CHRTZ support, and why does that matter?
The ISL95829CHRTZ supports both lossless DCR sensing (using inductor resistance) and precision resistor sensing. DCR eliminates sense resistor losses and improves efficiency; resistor sensing offers higher accuracy and immunity to temperature drift. This dual-mode capability gives designers flexibility to optimize the ISL95829CHRTZ-based VR for cost, efficiency, or accuracy without changing IC selection.
How does the ISL95829CHRTZ meet Intel PS4 low-power requirements?
The ISL95829CHRTZ achieves PS4 compliance through ultra-low quiescent supply current in deep-sleep states, enabled by internal circuit optimization and selective block shutdown. Its measured PS4 current is below Intel's specification limit, ensuring the ISL95829CHRTZ maintains system readiness while minimizing battery drain during suspend-to-RAM - critical for mobile device battery life.
Is the ISL95829CHRTZ pin-compatible with other Renesas IMVP9 controllers like ISL95869?
Yes, the ISL95829CHRTZ shares identical pinout, package, and functional specifications with the ISL95869, including SVID interface, VR_READY signaling, and current-sense inputs. This allows direct substitution in existing ISL95869 designs without layout changes - a verified compatibility confirmed in Renesas' official documentation for the ISL95829CHRTZ.
