Product details
Overview
ISL62882HRTZ-T from Renesas (formerly Intersil) is a dual-phase PWM buck controller IC for IMVP-6.5™-compliant CPU and GPU core voltage regulation. It delivers 0.5% system accuracy over temperature, supports 7-bit VID input (0.3V–1.5V in 12.5mV steps), integrates two gate drivers, and implements Robust Ripple Regulator (R3™) technology for fast transient response. It is used in notebook motherboard VRMs to supply power to Intel mobile processors.
For engineers reviewing the ISL62882HRTZ-T datasheet, ISL62882HRTZ-T pinout, ISL62882HRTZ-T application, or ISL62882HRTZ-T equivalent, key selection criteria include IMVP-6.5™ compliance, programmable 1-/2-phase operation, differential remote sensing, DCR/resistor current sensing support, and PSI#/DPRSLPVR dynamic phase control - all validated for -10°C to +100°C ambient operation in 40-lead 5×5 TQFN packaging.
Technical Context
The ISL62882HRTZ-T employs Intersil's patented R3™ modulator architecture, combining fixed-frequency PWM stability with hysteretic-like transient responsiveness by dynamically adjusting switching frequency during load transients. Its master-slave ripple capacitor topology ensures low phase jitter and superior dynamic current balance between phases.
It implements diode emulation mode with adaptive body diode conduction time reduction, split LGATE1 drivers for light-load efficiency, and FB2 compensation optimization for 1-phase operation. Current sensing supports both lossless inductor DCR and precision shunt resistor methods, thermally compensated via single NTC on the NTC pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulation Standard | Fully compliant with Intel IMVP-6.5™ specification for mobile CPU/GPU core power delivery. |
| Output Voltage Range | 0.300V to 1.500V via 7-bit VID interface (12.5mV steps); ±0.5% system accuracy over -10°C to +100°C ambient. |
| Phase Configuration | Programmable 1-phase (GPU) or 2-phase (CPU) operation; supports dynamic phase add/drop via PSI# and DPRSLPVR signals. |
| Switching Frequency | Nominal 300 kHz (adjustable 200–500 kHz via VW-to-COMP resistor); R3™ modulator enables variable frequency during transients. |
| Current Sensing | Dual-mode: lossless inductor DCR or discrete resistor; thermal compensation supported via single NTC thermistor on NTC pin. |
| Package & Temp Range | 40-lead 5×5 mm TQFN (L40.5x5); rated for -10°C to +100°C ambient operating temperature. |
| Gate Drivers | Two integrated high-side (UGATE1/UGATE2) and split low-side (LGATE1a/LGATE1b/LGATE2) drivers; UGATE sink/source ≥2.0 A, LGATE sink/source ≥1.0 A. |
Pinout & Package
ISL62882HRTZ-T is housed in a 40-lead, 5 mm × 5 mm, 0.5 mm pitch TQFN package with exposed GND pad on bottom. Pin numbering follows standard top-view orientation (Pin 1 at top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VID0–VID6 | Voltage identification input | 7-bit digital input (VID0 LSB) setting output voltage per IMVP-6.5™ table; supports on-the-fly VID changes. |
| FB / FB2 | Error amplifier inverting inputs | FB is primary feedback; FB2 enables optimized 1-phase compensation via internal switch that disconnects FB2 in 2-phase mode. |
| ISEN1 / ISEN2 | Phase current sense inputs | Differential inputs for per-phase current monitoring; ISEN2 pulled to VDD disables Phase 2. |
| UGATE1 / UGATE2 | High-side MOSFET gate drivers | Outputs driving gates of external high-side FETs; each supports ≥2.0 A sink/source with 23 ns deadtime to LGATE. |
| LGATE1a / LGATE1b / LGATE2 | Low-side MOSFET gate drivers | LGATE1a always active; LGATE1b disabled in deeper sleep (DPRSLPVR high); LGATE2 drives Phase 2 low-side FET. |
| VSEN / RTN | Differential remote voltage sense | VSEN connects to processor die VCC; RTN connects to die ground - enables precise die-level regulation, rejecting PCB IR drop. |
| IMON | Analog current monitor output | Current-source output proportional to total output current (e.g., 120 µA at 20 µA ISUM−); clamped at 1.15 V max. |
| PSI# / DPRSLPVR | Power state control inputs | PSI# asserts low for reduced load; DPRSLPVR high triggers deeper sleep - both trigger phase shedding and OCP threshold adjustment. |
Key Features
| Feature | Design Value |
|---|---|
| R3™ Robust Ripple Regulator | Variable-frequency modulation achieves faster load transient response than fixed-frequency PWM while maintaining 0.5% DC accuracy. |
| Split LGATE1 Driver Architecture | LGATE1a remains active; LGATE1b disables in deep sleep - reduces gate drive losses and improves light-load efficiency. |
| Adaptive Body Diode Conduction Control | Monitors PHASE node voltage to turn off LGATE before reverse current flows - minimizes body diode conduction loss in diode emulation mode. |
| User-selectable Overshoot Reduction | Configurable via RBIAS resistor choice (147kΩ or 47kΩ) to aggressively reduce output capacitance or disable for thermal-sensitive designs. |
| Differential Remote Sensing | VSEN/RTN pair referenced directly to processor die eliminates PCB trace resistance error - ensures accurate core voltage regulation under high-current loads. |
| Thermally Compensated DCR Sensing | Single NTC on NTC pin compensates for inductor DCR drift over temperature - maintains current-sense accuracy without additional sensors. |

FAQ
What is the operating temperature range for the ISL62882HRTZ-T?
The ISL62882HRTZ-T is rated for -10°C to +100°C ambient operating temperature. Its junction temperature must remain ≤+125°C under normal operation. This range targets mainstream consumer notebook applications, distinguishing it from the -40°C to +100°C ISL62882IRTZ-T variant. Thermal design should account for θJA = 32°C/W in typical 2-layer board layouts.
Does the ISL62882HRTZ-T support both CPU and GPU voltage regulation?
Yes, the ISL62882HRTZ-T supports both roles: configured as a 2-phase controller for Intel mobile CPU core power (via IMVP-6.5™ protocol), or as a 1-phase controller for GPU Vcore. Mode selection is determined by RBIAS resistor value and ISEN2 configuration - no hardware change is needed to switch between CPU and GPU applications.
How does the R3™ modulator in the ISL62882HRTZ-T improve transient response?
The R3™ modulator in the ISL62882HRTZ-T dynamically increases switching frequency during load steps by shortening the master clock period as COMP voltage rises - enabling sub-10 µs recovery from 50% load transients. Unlike fixed-frequency PWM, this preserves loop bandwidth at light loads while maintaining 0.5% DC accuracy via an integrated error amplifier.
Can the ISL62882HRTZ-T perform current sensing using inductor DCR?
Yes, the ISL62882HRTZ-T supports lossless inductor DCR current sensing on both phases via ISEN1 and ISEN2 pins. It includes thermal compensation circuitry that accepts a single NTC thermistor on the NTC pin to correct for DCR drift over temperature - eliminating need for separate temperature sensors or complex calibration.
What is the purpose of the FB2 pin on the ISL62882HRTZ-T?
The FB2 pin on the ISL62882HRTZ-T provides dedicated compensation network connection for 1-phase operation. An internal switch disconnects FB2 from FB in 2-phase mode; in 1-phase mode, FB2 connects to FB, allowing independent tuning of loop stability for optimal transient performance without affecting 2-phase behavior.
