Product details
Overview
ISL62882CIRTZ from Intersil is a multiphase PWM buck regulator IC designed as a core voltage controller for IMVP-6.5™-compliant mobile CPUs and GPUs. It supports 1- or 2-phase operation, delivers ±0.5% system accuracy over temperature, uses Robust Ripple Regulator (R3™) technology for variable-frequency transient response, and integrates two gate drivers in a 40-pin 5×5 mm TQFN package.
For engineers reviewing the ISL62882CIRTZ datasheet, ISL62882CIRTZ pinout, ISL62882CIRTZ application, or ISL62882CIRTZ equivalent, key selection considerations include IMVP-6.5™ compliance, dual-phase dynamic phase add/drop via PSI# and DPRSLPVR, differential remote sensing, DCR/resistor current sensing, and FB2-optimized 1-phase performance.
Technical Context
The ISL62882CIRTZ implements Intersil's R3™ modulator architecture, enabling variable switching frequency during load transients for sub-100 ns response and fixed-frequency operation at steady state. It supports both CPU and GPU Vcore configurations with programmable phase count and adaptive body diode conduction time reduction in diode emulation mode.
Current sensing is configurable via lossless inductor DCR (with single NTC thermal compensation) or precision shunt resistor. Voltage regulation employs differential remote sensing across the processor die, and output current reporting is provided on the IMON pin with ±5% accuracy over temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiphase CPU/GPU core voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL62883CIRTZ | 3-phase capable; higher max output current (60 A); identical R3™ modulator and IMVP-6.5™ compliance. | Targets higher-TDP CPUs (e.g., quad-core mobile H-series) requiring third phase for thermal headroom. | Select ISL62883CIRTZ when >40 A peak load or future-proofing for 3-phase scalability is required. |
| RT8803AGQW | 2-phase, IMVP-8 compliant; supports 0.25–1.5 V VID range; no FB2 pin; different phase-add logic. | Designed for newer Intel 10th/11th-gen platforms; lacks DPRSLPVR support and split LGATE optimization. | Choose RT8803AGQW only for IMVP-8 systems; not drop-in compatible due to VID timing and control signal differences. |
Compared with ISL62882CIRTZ, ISL62883CIRTZ extends phase count and current capability while retaining identical feature set and pinout, whereas RT8803AGQW targets next-generation IMVP-8 but requires redesign due to incompatible control signaling and absence of FB2 and split LGATE.

FAQ
What is the maximum output current supported by the ISL62882CIRTZ?
The ISL62882CIRTZ supports up to 40 A total output current in 2-phase configuration, with each phase delivering up to 20 A using appropriately rated external MOSFETs and inductors. Peak current capability depends on thermal design and layout; the device's overcurrent protection threshold scales dynamically with phase count and is validated per IMVP-6.5™ specifications in the ISL62882CIRTZ datasheet.
Does the ISL62882CIRTZ support both CPU and GPU Vcore regulation?
Yes, the ISL62882CIRTZ is fully configurable for either CPU or GPU core voltage regulation via external strap options and register settings. It meets all IMVP-6.5™ requirements for both domains, including PSI#, DPRSLPVR, VR_ON timing, and differential remote sensing-making ISL62882CIRTZ suitable for dual-role deployment in shared-platform notebook designs.
How does the R3™ modulator in the ISL62882CIRTZ improve transient response?
The R3™ modulator in the ISL62882CIRTZ achieves faster transient response by varying switching frequency during load steps-increasing frequency under sudden load increase to minimize output voltage deviation. Unlike fixed-frequency PWM, this architecture reduces typical transient undershoot/overshoot by >40% and cuts recovery time to <100 ns, as measured in ISL62882CIRTZ evaluation boards per FN7556.
Can the ISL62882CIRTZ operate in single-phase mode with optimized performance?
Yes, the ISL62882CIRTZ includes the FB2 function to optimize 1-phase mode performance, improving light-load efficiency and transient response. When configured for single-phase operation, FB2 adjusts loop compensation and gate drive strength-enabling ISL62882CIRTZ to maintain >90% efficiency at 100 mA and achieve tighter regulation versus standard 1-phase controllers without FB2.
What current sensing methods does the ISL62882CIRTZ support, and how is thermal drift compensated?
The ISL62882CIRTZ supports both precision shunt resistor and lossless inductor DCR current sensing. For DCR sensing, thermal drift is compensated using a single NTC thermistor connected to the THERM pin, enabling accurate current measurement across -10°C to +100°C ambient-critical for maintaining ISL62882CIRTZ's ±0.5% system accuracy in mobile thermal environments.
