Product details
Overview
ISL62884CIRTZ from Renesas (formerly Intersil) is a single-phase PWM buck regulator IC designed for IMVP-6™-compliant microprocessor core power supplies in mobile platforms. It integrates high- and low-side gate drivers, supports 7-bit VID input (0–1.500 V in 12.5 mV steps), achieves ±0.5% system voltage accuracy over temperature, uses R3™ ripple-based modulation for variable-frequency transient response, and enables differential remote sensing for precise die voltage regulation.
For engineers reviewing the ISL62884CIRTZ datasheet, ISL62884CIRTZ pinout, ISL62884CIRTZ application, or ISL62884CIRTZ equivalent, key selection considerations include IMVP-6™ compliance, DCR/resistor current sensing flexibility, adaptive body diode conduction time reduction, user-selectable overshoot reduction, and thermal compensation via NTC thermistor.
Technical Context
The ISL62884CIRTZ implements Intersil's Robust Ripple Regulator (R3™) topology, enabling load-dependent switching frequency variation to improve transient response while reducing light-load switching frequency for higher efficiency. Its modulator directly interprets DPRSLPVR signals to enter/exit diode emulation mode and reports real-time output current via the IMON pin.
Current sensing supports both lossless inductor DCR with NTC-based thermal compensation and precision shunt resistor methods. Differential remote sensing eliminates PCB trace IR drop errors, and adaptive body diode conduction time reduction minimizes conduction losses specifically during diode emulation operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-phase IMVP-6™ core regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL62883CIRTZ | Three-phase capable; higher peak current rating (45A vs. 35A); same R3™ modulator and VID interface. | Targeted at higher-power CPUs (e.g., quad-core mobile processors); requires additional phase layout and gate drive components. | Select ISL62883CIRTZ only when >30A continuous load or multi-phase scalability is required. |
| RT8802AGQW | Single-phase, IMVP-6.5 compliant; includes integrated MOSFETs; no external gate drivers needed; different VID mapping and IMON scaling. | Designed for simplified layout and lower component count; lacks DCR thermal compensation and differential remote sensing. | Choose RT8802AGQW for cost-sensitive, lower-complexity designs where IMVP-6.5 suffices and thermal compensation is not critical. |
Compared with ISL62884CIRTZ, ISL62883CIRTZ offers higher current capability but increases board area and BOM; RT8802AGQW integrates power stages but sacrifices IMVP-6™ precision features like DCR thermal compensation and differential sensing-making ISL62884CIRTZ optimal for thermally demanding, space-constrained IMVP-6™ notebook core rails.

FAQ
What is the maximum supported output current for ISL62884CIRTZ?
The ISL62884CIRTZ is rated for up to 35 A continuous output current when properly heatsinked and configured with appropriate external MOSFETs and inductors. This rating assumes VIN = 19 V, ambient temperature ≤ 60°C, and use of recommended 4×4 mm TQFN layout with thermal pad soldered to ground plane. Peak current capability depends on layout, airflow, and component selection-refer to thermal derating curves in FN7591 for specific conditions.
Does ISL62884CIRTZ support both DCR and resistor-based current sensing?
Yes, ISL62884CIRTZ supports dual current sensing methods: lossless inductor DCR sensing with optional NTC thermistor compensation for temperature drift, and precision shunt resistor sensing. The device auto-detects sensing method based on external component configuration-no register programming or pin strapping is required. Both methods feed into the same IMON current monitor output and OCP protection circuitry.
How does the R3™ modulation in ISL62884CIRTZ improve transient response?
The R3™ (Robust Ripple Regulator) modulation in ISL62884CIRTZ senses output ripple directly to control switching frequency dynamically. During load transients, it increases frequency to deliver more energy per unit time, reducing voltage deviation. At light loads, it lowers frequency to minimize switching losses. This eliminates reliance on error amplifier bandwidth alone-resulting in sub-microsecond response to 50% load steps without external compensation components.
Is ISL62884CIRTZ compatible with Intel's IMVP-6™ specification?
Yes, ISL62884CIRTZ is fully compliant with Intel's IMVP-6™ specification. It meets all mandatory requirements including VID decoding (7-bit, 12.5 mV steps), load-line regulation, DPRSLPVR-controlled diode emulation mode, IMON current reporting (100 mV/A nominal), and differential remote sensing. Compliance was verified per FN7591 test reports and confirmed in AN1545 evaluation board documentation.
What package type and lead finish does ISL62884CIRTZ use?
ISL62884CIRTZ uses a 28-lead, 4 mm × 4 mm TQFN package with an exposed thermal pad (EP). It is Pb-free and RoHS-compliant, with NiPdAu lead finish. The EP must be soldered to a dedicated PCB thermal pad connected to ground for optimal thermal performance and electrical stability-failure to do so may cause thermal shutdown or regulation inaccuracy.
