Product details
Overview
ISL62882CHRTZ-T from Renesas (formerly Intersil) is a dual-phase PWM buck regulator IC designed as a core voltage controller for IMVP-6.5™-compliant mobile CPUs and GPUs. It delivers 0.5% system accuracy over temperature, supports 7-bit VID input (0–1.500 V in 12.5 mV steps), and integrates two gate drivers in a 40-pin 5×5 mm TQFN package for notebook processor power delivery.
For engineers reviewing the ISL62882CHRTZ-T datasheet, ISL62882CHRTZ-T pinout, ISL62882CHRTZ-T application, or ISL62882CHRTZ-T equivalent, key selection considerations include IMVP-6.5™ compliance, PSI#/DPRSLPVR phase shedding support, DCR/resistor current sensing, differential remote sensing, and R3™ modulator transient response behavior.
Technical Context
The ISL62882CHRTZ-T implements Intersil's Robust Ripple Regulator (R3™) technology, enabling variable-frequency modulation during load transients for faster response and fixed-frequency reduction at light load to improve efficiency. Its split LGATE1 driver architecture and adaptive body diode conduction time reduction are specifically optimized for diode emulation mode operation.
It supports both CPU and GPU Vcore configurations via programmable 1- or 2-phase operation, responds to VR_ON timing per TB496, and uses differential remote sensing with thermal compensation via single NTC thermistor for DCR-based current sensing - all while maintaining IMVP-6.5™-specified load line regulation and PSI#-driven phase add/drop functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulation Accuracy | ±0.5% over temperature - ensures stable core voltage under thermal stress in thin-profile notebooks. |
| VID Input Range | 7-bit, 0–1.500 V in 12.5 mV steps - enables precise, on-the-fly voltage scaling for Intel mobile processors. |
| Phase Configuration | Programmable 1- or 2-phase - allows flexible design for CPU vs. GPU Vcore with dynamic phase shedding via PSI#. |
| Current Sensing | DCR or discrete resistor - supports lossless inductor sensing with single NTC thermal compensation for accuracy across operating range. |
| Modulator Type | R3™ (Robust Ripple Regulator) - delivers variable switching frequency during transients for <10 µs response and reduced output capacitance. |
| Package | 40-pin TQFN, 5×5×0.8 mm - enables high-density layout with exposed thermal pad for thermal management in space-constrained systems. |
| Overshoot Reduction | User-selectable - allows trade-off between capacitor count reduction and thermal stress mitigation in final design. |
Pinout & Package
ISL62882CHRTZ-T is housed in a 40-lead, 5×5 mm, 0.5 mm pitch TQFN package with exposed thermal pad (suffix "HRTZ-T" denotes this variant). Pin functions are validated per FN7556 Rev 3.00, Page 10 (Pin Description Table).

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiphase CPU/GPU core regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL62883CHRTZ-T | Same R3™ architecture and pinout; supports IMVP-7.0™ with extended VID range (0–1.525 V) and tighter load line tolerance. | Required for newer Intel 3rd-gen Core platforms; not backward-compatible with IMVP-6.5™-only BIOS. | Select ISL62883CHRTZ-T only if upgrading to IMVP-7.0™-compliant processors; otherwise ISL62882CHRTZ-T remains optimal. |
| RT8803AGQW | Single-chip 2-phase controller with integrated MOSFET drivers; lacks R3™ modulator - uses conventional constant-frequency PWM with slower transient response (~25 µs). | Targeted at cost-sensitive mainstream notebooks; does not support full IMVP-6.5™ PSI#/DPRSLPVR feature set. | Choose RT8803AGQW for non-IMVP-6.5™ designs where transient speed and specification compliance are secondary to BOM cost. |
Compared with ISL62883CHRTZ-T, the ISL62882CHRTZ-T provides exact IMVP-6.5™ compliance and superior transient response but lacks IMVP-7.0™ extensions; versus RT8803AGQW, it delivers verified specification adherence and faster load-step recovery at higher system integration complexity.

FAQ
What is the primary function of the ISL62882CHRTZ-T in a mobile computing system?
The ISL62882CHRTZ-T serves as a dual-phase PWM buck regulator IC that delivers precisely regulated core voltage to Intel mobile CPUs and GPUs in compliance with IMVP-6.5™ specifications. It manages dynamic voltage scaling via 7-bit VID, performs phase shedding using PSI# and DPRSLPVR signals, and ensures tight regulation accuracy (±0.5%) across temperature - making it essential for stable operation in ultrabooks and gaming laptops. The ISL62882CHRTZ-T integrates gate drivers and supports both DCR and resistor-based current sensing.
Does the ISL62882CHRTZ-T support both CPU and GPU Vcore configurations?
Yes, the ISL62882CHRTZ-T is programmable for either CPU or GPU Vcore operation through configuration pins and firmware settings. It supports 1-phase mode (optimized via FB2) for GPU applications and 2-phase mode for CPU core power, with automatic phase shedding triggered by PSI# and DPRSLPVR signals. The ISL62882CHRTZ-T maintains IMVP-6.5™ compliance in both modes, including load line regulation, differential remote sensing, and thermal-compensated current monitoring.
How does the R3™ modulator in the ISL62882CHRTZ-T improve transient response?
The R3™ (Robust Ripple Regulator) modulator in the ISL62882CHRTZ-T dynamically adjusts switching frequency during load transients - increasing frequency for faster response and reducing it at light load to improve efficiency. This architecture achieves sub-10 µs transient recovery, significantly outperforming fixed-frequency PWM controllers. The ISL62882CHRTZ-T leverages this behavior to maintain tight output voltage regulation during CPU turbo boost or GPU shader load spikes without excessive output capacitance.
Can the ISL62882CHRTZ-T use inductor DCR for current sensing, and how is thermal drift compensated?
Yes, the ISL62882CHRTZ-T supports lossless inductor DCR current sensing using its differential SNS+/SNS− inputs. Thermal drift of DCR is compensated by connecting a single NTC thermistor to the THRM pin, enabling real-time correction of sense gain across temperature. This method eliminates the need for discrete current-sense resistors while maintaining ±0.5% system accuracy - a capability confirmed in FN7556 Rev 3.00. The ISL62882CHRTZ-T also supports precision shunt resistor sensing as an alternative.
What package type and thermal characteristics does the ISL62882CHRTZ-T have?
The ISL62882CHRTZ-T uses a 40-lead, 5×5 mm, 0.5 mm pitch TQFN package with an exposed thermal pad (denoted by "HRTZ-T" suffix), compliant with RoHS and Pb-free standards. Its thermal resistance θJA is 32°C/W (typical, JEDEC standard board), enabling effective heat dissipation in thin-profile notebooks. The ISL62882CHRTZ-T requires proper PCB copper pour under the thermal pad and recommended reflow profile per FN7556 to ensure reliability and performance consistency.
