Product details
Overview
ISL95829AHRTZ from Renesas Electronics is a 3-phase voltage regulator controller with integrated gate drivers, compliant with Intel IMVP9 specifications for CPU core power delivery. It supports 1-/2-/3-phase configurations, uses SVID interface for CPU communication, and delivers 0.5% system accuracy over temperature with DCR or resistor-based current sensing.
For engineers reviewing the ISL95829AHRTZ datasheet, ISL95829AHRTZ pinout, ISL95829AHRTZ application, or ISL95829AHRTZ equivalent, key selection criteria include IMVP9 compliance, R3™ modulator transient response, PSYS monitoring capability, and RoHS-compliant 4×4 TQFN-40 package integration in high-density notebook power designs.
Technical Context
The ISL95829AHRTZ implements Renesas' Robust Ripple Regulator (R3™) topology, enabling variable switching frequency (up to 750 kHz), adaptive body diode conduction time reduction, and Diode Emulation mode for light-load efficiency. Its SVID interface handles dynamic voltage scaling and telemetry reporting per IMVP9 requirements.
It supports dual current sensing methods-lossless DCR sensing with single NTC thermistor compensation and precision resistor sensing-and includes differential remote voltage sense, programmable VBOOT, ICCMAX, slew rate, and PSYS monitoring via alternate VSYS mode to meet Intel PS4 power state compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase VR controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95869HRZZ | Same R3™ architecture and IMVP9 compliance; differs in pinout (48-pin QFN) and lacks PSYS monitoring support. | Targeted at higher-channel count or legacy motherboard layouts requiring larger footprint. | Select ISL95869HRWZZ only when PSYS monitoring is not required and board layout accommodates 6×6 mm QFN. |
| RTQ2136B-QA | Monolithic 3-phase controller with integrated drivers; supports IMVP9 but uses different SVID implementation and no DCR thermistor compensation. | Designed for automotive-grade reliability; requires external NTC bypass for DCR temp compensation. | Choose RTQ2136B-QA only for AEC-Q100 qualified designs where industrial temperature range and qualification outweigh DCR flexibility. |
Compared with ISL95869HRWZZ and RTQ2136B-QA, the ISL95829AHRTZ uniquely combines PSYS monitoring, 4×4 TQFN-40 packaging, and full DCR+NTC compensation in a single IMVP9-compliant controller-making it optimal for next-gen Ultrabook and fanless tablet VRMs where space, acoustics, and PS4 compliance are co-constrained.

FAQ
What is the primary function of the ISL95829AHRTZ in an Intel IMVP9 platform?
The ISL95829AHRTZ serves as the main 3-phase voltage regulator controller for Intel CPU core power rails. It manages dynamic voltage scaling, current sensing, and transient response via SVID interface. Its R3™ modulator architecture and integrated gate drivers enable precise, low-noise regulation-making ISL95829AHRTZ essential for meeting IMVP9 specification requirements in Ultrabooks and tablets.
Does the ISL95829AHRTZ support both DCR and resistor-based current sensing?
Yes, the ISL95829AHRTZ supports dual current sensing methods: lossless inductor DCR sensing with single NTC thermistor compensation for temperature drift correction, and precision shunt resistor sensing. This flexibility allows designers to optimize cost, accuracy, and thermal performance-key advantages of the ISL95829AHRTZ in high-volume mobile platforms.
What package type and pin count does the ISL95829AHRTZ use?
The ISL95829AHRTZ uses a RoHS-compliant 4×4 mm TQFN-40 package with exposed thermal pad. This compact footprint supports high-density PCB layouts in space-constrained devices. All 40 pins-including SVID_DATA, SVID_CLK, PHASEx_OUT, VR_READY, and PSYS_MON-are electrically and thermally optimized for multi-phase VR applications, distinguishing ISL95829AHRTZ from larger-footprint alternatives.
How does the ISL95829AHRTZ achieve PS4 power state compliance?
The ISL95829AHRTZ achieves PS4 compliance through its alternate VSYS mode, which enables system-level input power (PSYS) monitoring. This feature, combined with low quiescent current in deep-sleep states and precise voltage regulation, satisfies Intel's stringent PS4 requirements for ultra-low-power idle modes-confirming ISL95829AHRTZ as a validated solution for modern energy-efficient notebooks.
Is the ISL95829AHRTZ pin-compatible with other ISL95xxx controllers like the ISL95869?
No, the ISL95829AHRTZ is not pin-compatible with the ISL95869 or other members of the ISL95xxx family. It uses a unique 40-pin TQFN-40 layout optimized for compactness and thermal performance, whereas ISL95869 variants use 48-pin QFN packages with different pin assignments. Board redesign is required when substituting ISL95829AHRTZ-this distinction is critical for layout planning and must be verified before migration.
