Product details
Overview
ISL6262IRZ-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™ modulator architecture, 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 interleaved operation for reduced ripple and enhanced transient response in laptop CPU power delivery.
For engineers reviewing the ISL6262IRZ-T datasheet, ISL6262IRZ-T pinout, ISL6262IRZ-T application, or ISL6262IRZ-T equivalent, key selection considerations include IMVP-6 compliance, dual-phase DCR/resistive current sensing support, -40°C to 100°C industrial temperature rating, thermal monitoring via NTC input, and seamless transition between 2-phase CCM, 1-phase CCM, and 1-phase DCM modes.
Technical Context
The ISL6262IRZ-T employs R3 Technology™-a hybrid modulator synthesizing noise-free ripple current analogs for hysteretic PWM control-enabling variable switching frequency during load transients and achieving faster response than fixed-frequency PWM regulators. Its error amplifier provides 90dB DC gain and 18MHz GBW to maintain tight regulation under dynamic VID changes.
It implements Intel IMVP-6 smart voltage positioning via 7-bit VID interface, supports differential remote die sensing (VDIFF/VSEN/RTN), and uses VSUM-based droop control for accurate load-line compliance. Current sensing is configurable via lossless DCR or precision resistive methods, with NTC compensation for thermal drift in DCR sensing.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6262CRZ-T | Same silicon, rated for -10°C to 100°C ambient - lacks extended low-temp capability | Suitable only for commercial-temperature laptops; not qualified for industrial or automotive cold environments | Select ISL6262IRZ-T when operation below -10°C is required; CRZ-T offers identical functionality at lower cost for consumer notebooks. |
| RT8802A | Single-chip IMVP-6 controller with integrated MOSFET drivers but no R3 modulator - fixed-frequency PWM with slower transient response | Used in cost-sensitive mainstream notebooks; lacks DCM mode and NTC compensation | Choose ISL6262IRZ-T for superior transient performance and deeper-sleep efficiency; RT8802A suits budget platforms with relaxed regulation specs. |

FAQ
What is the operating temperature range of the ISL6262IRZ-T?
The ISL6262IRZ-T is rated for industrial ambient temperatures from -40°C to 100°C, with a maximum junction temperature of 125°C. This extended range distinguishes it from the commercial-grade ISL6262CRZ-T (-10°C to 100°C) and makes the ISL6262IRZ-T suitable for ruggedized laptop designs and industrial embedded systems where cold-start reliability is critical.
Does the ISL6262IRZ-T support both DCR and resistive current sensing?
Yes, the ISL6262IRZ-T supports both lossless inductor DCR current sensing and precision resistive current sensing. For DCR sensing, it includes an internal 60µA NTC bias current and dedicated NTC pin for thermal compensation of copper winding resistance drift. For resistive sensing, it accepts Kelvin-connected sense resistors at ISEN1/ISEN2 with <1mV imbalance tolerance - enabling flexible layout in high-current mobile CPU power stages.
How does the ISL6262IRZ-T implement IMVP-6 load-line regulation?
The ISL6262IRZ-T implements IMVP-6 load-line regulation using its internal droop amplifier. The summed channel currents at VSUM generate a proportional voltage at DROOP relative to VO, which is fed into a differential amplifier with DFB as reference. This creates a programmable negative output impedance that drops output voltage linearly with load current - matching Intel's specified load-line slope without external components.
What is the purpose of the FB2 pin on the ISL6262IRZ-T?
The FB2 pin on the ISL6262IRZ-T provides separate compensation network access for single-phase operation. An internal switch connects FB2 to FB during 1-phase mode and disconnects it during 2-phase mode. This allows designers to optimize loop stability independently for each operating mode - ensuring robust regulation during PSI#-triggered phase shedding and preventing oscillation during mode transitions.
Can the ISL6262IRZ-T be used in new designs given its 2006 datasheet date?
Yes, the ISL6262IRZ-T remains actively manufactured and supported by Renesas for legacy mobile CPU platforms. Its IMVP-6 compliance, proven reliability in high-volume laptops, and continued availability through authorized distributors make the ISL6262IRZ-T viable for maintenance, replacement, and long-lifecycle industrial designs - especially where backward compatibility with Pentium M/Core Duo ecosystems is required.
