Product details
Overview
ISL6262CRZ-T from Renesas (formerly Intersil) is a two-phase buck core voltage regulator IC implementing Intel IMVP-6 protocol for mobile CPUs, featuring integrated 2A gate drivers, R3™ Robust Ripple Regulator modulator, 0.5% system output voltage accuracy over temperature, and dynamic phase add/drop across 0.300V–1.500V VID range. It delivers up to 50A output with DCR or resistive current sensing in notebook CPU power delivery.
For engineers reviewing the ISL6262CRZ-T datasheet, ISL6262CRZ-T pinout, ISL6262CRZ-T application, or ISL6262CRZ-T equivalent, key selection criteria include IMVP-6 compliance, two-phase CCM/DCM mode transition behavior, differential remote die sensing, thermal compensation via NTC, and 48-pin 7×7 QFN package compatibility with high-density mobile VR designs.
Technical Context
The ISL6262CRZ-T employs R3 Technology™-a hybrid modulator synthesizing noise-free ripple current analogs for hysteretic PWM control-enabling faster transient response than fixed-frequency PWM while maintaining 0.5% voltage regulation accuracy. Its dual-channel interleaved architecture operates at 200–500kHz nominal frequency (set via VW pin resistor), doubling effective ripple frequency to reduce output capacitor count and PCB area.
It supports three operational modes under IMVP-6 control: two-phase continuous conduction mode (CCM) at heavy load, one-phase CCM when PSI# is asserted, and single-phase diode-emulation discontinuous conduction mode (DCM) during deeper sleep (DPRSLPVR active). Current sensing uses either lossless DCR with NTC thermal compensation or precision shunt resistors, with static/dynamic current sharing enforced via ISEN1/ISEN2 inputs and VSUM summation node.
Key Specifications

| UGATE1/LGATE1/PHASE1/BOOT1 UGATE2/LGATE2/PHASE2/BOOT2 | Phase 1 & 2 gate drive outputs | Drive external high-side and low-side MOSFETs; UGATE/LGATE sink/source ≥2A; BOOT pins integrate bootstrap diodes. |
| PGOOD, VR_TT#, CLK_EN# | Open-drain status outputs | PGOOD asserts after soft-start and regulation lock; VR_TT# pulls down on overtemperature; CLK_EN# enables system PLL post-regulation. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar two-phase IMVP-6 core regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6262IRZ-T | Wider operating temperature range (–40°C to +100°C) and relaxed system accuracy (±0.8%) vs ISL6262CRZ-T (–10°C to +100°C, ±0.5%). | Suitable for extended-temperature industrial or automotive-adjacent deployments where tighter voltage accuracy is less critical than cold-start capability. | Select ISL6262IRZ-T only if ambient operation below –10°C is required; otherwise ISL6262CRZ-T offers superior accuracy for commercial notebooks. |
| RT8803AGQW | Single-chip IMVP-6 controller with integrated MOSFET drivers and 300kHz fixed frequency; lacks R3 modulator, DCR thermal compensation, and programmable soft-start slew rate. | Targeted at cost-sensitive mainstream notebooks where transient performance and thermal compensation are secondary to BOM reduction. | Choose RT8803AGQW for simplified layout and lower component count; retain ISL6262CRZ-T when IMVP-6 compliance, 0.5% accuracy, or NTC-compensated DCR sensing is mandatory. |
Compared with ISL6262IRZ-T, the ISL6262CRZ-T trades extended temperature rating for tighter 0.5% voltage accuracy and lower thermal drift-critical for high-performance mobile CPUs. Against RT8803AGQW, it provides superior transient response via R3 Technology™ and robust thermal compensation, justifying its use in premium ultrabooks and mobile workstations.

FAQ
What is the maximum output current supported by the ISL6262CRZ-T?
The ISL6262CRZ-T is designed for up to 50A total output current in two-phase operation, as validated in typical performance curves using 2×IRF7821/2×IRF7832 per phase. Actual achievable current depends on external MOSFET selection, PCB thermal design, and input voltage (5–21V). Its R3 modulator and current-sharing circuitry ensure stable current division between phases even at full load.
Does the ISL6262CRZ-T support both DCR and resistive current sensing?
Yes, the ISL6262CRZ-T supports both lossless inductor DCR current sensing-with built-in NTC thermal compensation via the NTC pin-and precision resistive current sensing using external shunt resistors. The ISEN1 and ISEN2 pins accept either signal type, and the internal droop amplifier uses the summed VSUM signal to implement IMVP-6 load-line regulation and overcurrent protection.
How does the ISL6262CRZ-T handle phase transitions during CPU sleep states?
The ISL6262CRZ-T uses IMVP-6 control signals-PSI#, DPRSLPVR, and DPRSTP#-to execute smooth, glitch-free phase transitions: PSI# assertion triggers transition from two-phase CCM to one-phase CCM; DPRSLPVR high initiates entry into single-phase diode-emulation DCM for deepest sleep. Internal counters reject sub-2-cycle glitches, and R3 Technology™ maintains regulated output throughout transitions.
What is the purpose of the SOFT pin on the ISL6262CRZ-T?
The SOFT pin on the ISL6262CRZ-T serves as the non-inverting input to the error amplifier and sets the output voltage slew rate during startup and VID transitions. A capacitor from SOFT to GND determines the soft-start ramp (e.g., 15nF yields ~2.5mV/µs), preventing inrush current and ensuring controlled CPU boot sequencing. It also functions as the soft-slew node during dynamic VID changes.
Is the ISL6262CRZ-T RoHS compliant and compatible with lead-free reflow?
Yes, the ISL6262CRZ-T is RoHS compliant and features Intersil's Pb-free plus anneal construction: 100% matte tin termination, Pb-free molding compound, and die attach materials. It meets or exceeds IPC/JEDEC J-STD-020 moisture sensitivity and peak reflow requirements for both SnPb and lead-free soldering processes, with MSL rating appropriate for Pb-free peak temperatures.
