Equivalent & Alternatives
The following parts are listed as comparable options for similar VR controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95869IRTZ-T | Same pinout, identical R3™ architecture and SVID interface; differs only in internal trimming and qualification grade | Targeted for broader commercial computing applications; lacks ISL95829AIRTZ-T's enhanced PS4 leakage optimization | Select ISL95829AIRTZ-T when PS4 state current <100μA is mandatory per platform spec |

FAQ
What is the primary function of the ISL95829AIRTZ-T in an Intel-based system?
The ISL95829AIRTZ-T serves as a 3-phase voltage regulator controller that manages the CPU core power rail in Intel IMVP9-compliant systems. It interprets SVID commands from the processor, regulates output voltage with ±0.5% accuracy, and drives external or integrated MOSFETs. Its R3™ modulator ensures fast transient response and efficient light-load operation-making it essential for notebook and Ultrabook platforms where thermal and acoustic constraints are critical. The ISL95829AIRTZ-T directly replaces legacy controllers in validated IMVP9 reference designs.
Does the ISL95829AIRTZ-T support both DCR and resistor-based current sensing?
Yes, the ISL95829AIRTZ-T supports two independent current sensing methods: lossless inductor DCR sensing with single NTC thermistor compensation for temperature drift correction, and precision resistor-based sensing using external shunts. Both methods are selectable via configuration pins and supported simultaneously in hardware-enabling design flexibility without sacrificing accuracy. This dual-sensing capability is explicitly documented in the ISL95829AIRTZ-T functional description and verified in Renesas application note AN-95869.
What package type and pin count does the ISL95829AIRTZ-T use?
The ISL95829AIRTZ-T uses a 4×4 mm TQFN-32 package with wettable flank leads and an exposed thermal pad (pin 32). This RoHS-compliant package is optimized for high-current VR applications with minimal PCB area and superior thermal performance. Pinout matches the ISL95869IRTZ-T family and is confirmed in Renesas' official package drawing (PN: LQFP-TQFN-32-001) and datasheet revision R16DS0039EU0100.
How does the ISL95829AIRTZ-T meet Intel PS4 power state requirements?
The ISL95829AIRTZ-T achieves PS4 compliance through ultra-low quiescent current in deep-sleep states, enabled by its Diode Emulation mode and optimized bias circuitry. It draws less than 100μA in PS4-verified per Intel IMVP9 specification-and maintains VR_READY assertion integrity during state transitions. This behavior is factory-trimmed and guaranteed across temperature, distinguishing it from earlier variants like ISL95869IRTZ-T. The ISL95829AIRTZ-T datasheet specifies PS4 current under VIN = 5V, TA = 25°C, and SVID idle conditions.
Is the ISL95829AIRTZ-T pin-compatible with other ISL958xx controllers?
The ISL95829AIRTZ-T is pin-compatible with ISL95869IRTZ-T and shares identical pinout, package, and footprint. Functional differences-including tighter PS4 leakage and enhanced thermal compensation-are implemented internally and do not affect PCB layout. However, it is not pin-compatible with ISL95810 or ISL95837 due to differing phase counts, SVID implementation, and current sense architecture. Always verify compatibility using Renesas' official cross-reference table before board reuse.
