Equivalent & Alternatives
The following parts are listed as comparable options for similar IMVP9 voltage regulator controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95869HRTZ-T | Same die, identical pinout and electrical specs - differs only in tape-and-reel packaging and part marking suffix. | No functional difference; both qualify for same IMVP9 designs and layout footprints. | Select ISL95869HRTZ-T when sourcing from legacy inventory or distributor stock with matching reel format. |
| RTQ2133BGQW | Monolithic 3-phase controller with integrated high- and low-side MOSFETs; no external drivers needed - higher integration but lower max current (45 A vs. 75 A). | Better suited for mid-range mobile platforms where board space is more constrained than thermal headroom. | Choose RTQ2133BGQW for simplified BOM and reduced layout complexity in sub-45 A applications. |
Compared with ISL95829AHRTZ-T, ISL95869HRTZ-T offers identical performance and compatibility, while RTQ2133BGQW trades external driver flexibility for monolithic integration - making the former ideal for high-current, thermally optimized VRMs and the latter for space-limited, medium-power designs.

The ISL95829AHRTZ-T delivers precise, dynamically adjustable output voltage with fast transient response, remote sensing, and PSYS monitoring - all critical for stable operation of modern Intel processors.
Does the ISL95829AHRTZ-T support both DCR and resistor-based current sensing?
Yes, the ISL95829AHRTZ-T supports dual current sensing methods: lossless inductor DCR sensing with single NTC thermistor compensation for temperature drift correction, and precision resistor-based sensing for higher accuracy where DCR variation is unacceptable. Both methods are selectable via configuration pins and supported simultaneously in the same design, allowing designers to optimize for cost, accuracy, or thermal performance based on platform requirements.
What package type and pin count does the ISL95829AHRTZ-T use?
The ISL95829AHRTZ-T uses a 40-pin, 4×4 mm TQFN package with exposed thermal pad (EP), RoHS-compliant and optimized for high-density motherboard layouts. This package supports efficient thermal dissipation and low-inductance power routing, and its pinout is fully compatible with other members of the ISL958xx IMVP9 controller family, including ISL95869HRTZ-T.
How does the R3™ modulator in the ISL95829AHRTZ-T improve VRM performance?
The R3™ modulator in the ISL95829AHRTZ-T enables variable switching frequency that scales with load transients, achieving faster settling time and improved light-load efficiency via Diode Emulation mode. Unlike fixed-frequency modulators, R3™ dynamically adjusts frequency to maintain optimal efficiency across 0–100% load range - reducing output capacitance needs and eliminating audible noise without sacrificing regulation accuracy or transient response.
Is the ISL95829AHRTZ-T compatible with Intel PS4 power state requirements?
Yes, the ISL95829AHRTZ-T meets Intel PS4 power state requirements through ultra-low quiescent supply current and support for alternate VSYS mode to monitor system input power (PSYS). Its low-power design enables deep-sleep states in mobile platforms while maintaining VR_READY signaling integrity - a mandatory feature for IMVP9-compliant platforms targeting Intel's latest energy efficiency standards.
