Product details
Overview
ISL6262ACRZ-T from Renesas (formerly Intersil) is a two-phase buck core controller implementing Intel IMVP-6+ protocol with integrated 2A gate drivers, supporting 0.300V–1.500V output via 7-bit VID, ±0.5% system accuracy over temperature, and dynamic phase shedding for CPU voltage regulation in mobile platforms.
For engineers reviewing the ISL6262ACRZ-T datasheet, ISL6262ACRZ-T pinout, ISL6262ACRZ-T application, or ISL6262ACRZ-T equivalent, key selection criteria include IMVP-6+ compliance, R3 Technology™ modulator for fast transient response, DCR/resistive current sensing support, differential remote sensing, and thermal/power monitoring outputs.
Technical Context
The ISL6262ACRZ-T uses patented R3 Technology™-a hybrid modulator synthesizing noise-free ripple current analogs to drive hysteretic comparators-enabling variable switching frequency during load transients and achieving faster response than fixed-frequency PWM controllers. It supports both continuous conduction mode (CCM) and diode emulation at light load.
It implements Intel Mobile Voltage Positioning (IMVP-6+) with precise load-line droop control, dual-phase current balancing, and seamless transitions between 2-phase CCM, 1-phase CCM, and deeper-sleep modes via DPRSLPVR, PSI#, and DPRSTP# signals-all while maintaining 0.5% output voltage accuracy across -10°C to +100°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| System Accuracy | ±0.5% over temperature (0°C to +100°C) for VID = 0.75V–1.5V; ensures tight regulation under thermal stress without calibration. |
| Switching Frequency | Nominal 300 kHz (100–500 kHz adjustable via VW pin resistor); balances efficiency, component size, and EMI in portable computing power stages. |
| Gate Drive Capability | 2A source/sink per UGATE/LGATE; drives high-side and low-side MOSFETs directly without external buffers in compact QFN layout. |
| Current Sensing | Supports lossless DCR sensing (with NTC thermal compensation) or precision resistive sensing; maintains accurate load-line and OCP across temperature. |
| Protection Features | Programmable overcurrent (via OCSET), overvoltage (200 mV trip), undervoltage (-300 mV trip), thermal shutdown (VR_TT#), and PGOOD with 7.6 ms delay. |

| LGATE1/LGATE2 | Lower gate driver outputs | Drive low-side MOSFET gates with 4A sink capability; optimized for fast turn-off in synchronous buck stages. |
| VSEN/RTN | Differential remote sense inputs | Enable Kelvin sensing at CPU die; eliminate PCB trace IR drop for ±0.5% regulation accuracy at point-of-load. |
| PSI#, DPRSLPVR, DPRSTP# | IMVP-6+ power state control inputs | Coordinate phase shedding (PSI#), deeper sleep entry (DPRSLPVR), and slow wake-up (DPRSTP#) per Intel specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar two-phase IMVP-6+ core controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the operating temperature range for the ISL6262ACRZ-T?
The ISL6262ACRZ-T is rated for commercial operation from -10°C to +100°C ambient temperature. Its junction temperature must remain ≤+125°C under normal operation. This range aligns with Intel Santa Rosa platform requirements and supports deployment in ultraportable notebooks without active cooling augmentation. The ISL6262ACRZ-T datasheet specifies thermal resistance θJA = 29°C/W and θJC = 4.5°C/W for the 7×7 mm QFN package.
Does the ISL6262ACRZ-T support both DCR and resistive current sensing?
Yes, the ISL6262ACRZ-T supports both lossless inductor DCR sensing-with built-in NTC thermal compensation-and precision resistive current sensing using external sense resistors. The DCR path uses ISEN1/ISEN2 inputs and VSUM summation, while resistive sensing connects directly to the same pins with appropriate RC filtering. Both methods feed the droop amplifier and overcurrent protection circuitry, ensuring consistent load-line behavior and OCP threshold accuracy across temperature.
How does the R3 Technology™ modulator in the ISL6262ACRZ-T improve transient response?
The R3 Technology™ modulator in the ISL6262ACRZ-T synthesizes clean analogs of inductor ripple current and applies them to hysteretic comparators-enabling variable switching frequency during load transients. Unlike fixed-frequency PWM controllers, this architecture increases frequency under step-load conditions, delivering faster voltage recovery (<5 µs typical) and lower peak deviation. The ISL6262ACRZ-T achieves this while retaining 0.5% DC accuracy via its dedicated error amplifier and feedback loop.
What is the function of the PMON pin on the ISL6262ACRZ-T?
The PMON pin on the ISL6262ACRZ-T provides an analog voltage output proportional to the product of VSEN and the droop voltage (DROOP − VO), enabling real-time estimation of instantaneous CPU core power. Its output ranges from 0.308V to 1.722V depending on load and VID setting, with sourcing/sinking capability up to ±2 mA. This signal can be fed directly into an external ADC for firmware-based power budgeting, thermal management, or adaptive performance tuning in mobile platforms.
Can the ISL6262ACRZ-T operate in single-phase mode, and how is it controlled?
Yes, the ISL6262ACRZ-T automatically transitions to single-phase CCM mode when the PSI# input is asserted low, indicating reduced CPU load. It also supports forced single-phase operation by pulling ISEN2 to 5V. During single-phase operation, the FB2 compensation network activates while FB remains active, optimizing loop stability. The transition is seamless-no reconfiguration delay-and maintains full IMVP-6+ compliance, including load-line droop and voltage accuracy, in both 1-phase and 2-phase configurations.
