Product details
Overview
ISL6262CRZ-TK from Intersil is a two-phase buck core voltage regulator implementing Intel IMVP-6 protocol with integrated 2A gate drivers, 0.5% system output voltage accuracy over temperature (0.300V–1.500V), R3 Technology™ modulator for fastest transient response, and dynamic phase add/drop for CPU active/deeper-sleep mode transitions in mobile computing platforms.
For engineers reviewing the ISL6262CRZ-TK datasheet, ISL6262CRZ-TK pinout, ISL6262CRZ-TK application, or ISL6262CRZ-TK equivalent, key selection considerations include IMVP-6 compliance, dual-phase DCR/resistive current sensing support, differential remote die sensing, programmable switching frequency (200–500 kHz), and thermal monitoring via NTC input.
Technical Context
The ISL6262CRZ-TK employs R3 Technology™-a hybrid modulator synthesizing noise-free ripple current analogs to enable hysteretic PWM timing with fixed-frequency error amplifier control-delivering lower output ripple and faster load transient response than conventional PWM or pure hysteretic controllers. It supports both lossless DCR and precision resistive current sensing, with single NTC thermistor compensation for DCR drift.
Its IMVP-6 interface includes 7-bit VID inputs (12.5 mV steps), PSI#, DPRSTP#, and DPRSLPVR signals to orchestrate seamless transitions between two-phase CCM, one-phase CCM, and one-phase DCM modes-enabling optimized efficiency across 0–50 A load range while maintaining ±0.5% regulation accuracy at 0.75–1.5 V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | 0.300 V to 1.500 V via 7-bit VID; enables precise Intel IMVP-6 core voltage positioning with 12.5 mV resolution. |
| System Accuracy | ±0.5 % over temperature (−10°C to 100°C) for VID = 0.75–1.5 V; ensures stable CPU operation under thermal stress without calibration. |
| Switching Frequency | 200–500 kHz, user-programmable via resistor on VW pin; balances EMI, efficiency, and component size for mobile VRM designs. |
| Gate Drive Capability | 2 A source/sink per UGATE/LGATE; drives high-side and low-side MOSFETs directly without external buffers in compact QFN layout. |
| Current Sensing | Supports both inductor DCR (with NTC thermal compensation) and discrete shunt resistor methods; eliminates need for power-wasting sense resistors or complex compensation networks. |
| Protection Features | Programmable overcurrent (via OCSET), overvoltage (200 mV trip), undervoltage (−300 mV trip), and thermal shutdown (NTC-based); prevents CPU damage during fault conditions. |
| Remote Sensing | Differential amplifier (VDIFF/VSEN/RTN) referenced to CPU die; corrects for PCB IR drop to maintain true die-level voltage regulation per IMVP-6 spec. |
Pinout & Package
ISL6262CRZ-TK is housed in a Pb-free 48-lead 7 mm × 7 mm QFN package (PKG DWG # L48.7x7) with exposed thermal pad. The package supports reflow soldering per IPC/JEDEC J-STD-020 MSL level matching Pb-free peak temperatures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VID0–VID6 | 7-bit digital voltage identification input | Directly sets core output voltage per IMVP-6 table; LSB = VID0, MSB = VID6; supports on-the-fly VID changes during operation. |
| PSI#, DPRSTP#, DPRSLPVR | IMVP-6 power state control inputs | Orchestrate phase shedding (PSI#), deeper sleep entry/exit timing (DPRSTP#, DPRSLPVR), and automatic mode transitions without firmware intervention. |
| UGATE1/2, LGATE1/2 | High-side and low-side MOSFET gate drivers | Integrated 2 A drivers eliminate external gate buffers; reduce layout complexity and parasitic inductance in high-frequency VRMs. |
| VSEN, RTN, VDIFF | Differential remote voltage sense interface | Enables accurate regulation at CPU die by rejecting PCB trace resistance; required for IMVP-6 compliance and stable high-current operation. |
| ISEN1, ISEN2, VSUM, DROOP | Per-phase and summed current sensing nodes | Supports static/dynamic current sharing and IMVP-6 load-line droop; DROOP pin provides high-bandwidth current-derived signal for protection and compensation. |
| NTC, RBIAS | Thermal compensation and internal reference setup | NTC input enables copper winding resistance drift correction for DCR sensing; RBIAS (147 kΩ to GND) sets internal current reference for OCSET and thermal thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| R3 Technology™ Modulator | Combines hysteretic timing with error amplifier control to achieve <10 µs load transient response while maintaining 0.5% DC accuracy-critical for modern CPU burst loads. |
| Dynamic Phase Management | Automatically transitions between 2-phase CCM → 1-phase CCM → 1-phase DCM based on PSI# and DPRSLPVR, reducing quiescent power by >40% at light load without sacrificing transient readiness. |
| Differential Remote Sensing | VSEN/RTN/VDIFF path achieves <1 mV sensing error over board traces up to 100 mm, ensuring CPU die voltage stays within IMVP-6 ±1% tolerance window. |
| DCR Current Sensing w/ NTC Compensation | Eliminates power loss and board space of shunt resistors; NTC network maintains <2% current measurement error from −10°C to 100°C ambient. |
| Programmable Soft-Start Slew Rate | SOFT pin capacitor sets output voltage ramp rate (e.g., 2.5 mV/µs with 15 nF); prevents inrush current and ensures controlled CPU boot sequencing. |

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 |
|---|---|---|---|
| ISL6262CRZ | Same silicon, identical electrical specs; differs only in tape-and-reel packaging (no -TK suffix) and absence of factory-set reel orientation marking. | No functional difference; suitable for same PCBs and firmware; used in non-automated manual assembly or small-batch prototyping. | Select ISL6262CRZ-TK for high-volume SMT lines requiring standardized reel orientation and automated vision inspection alignment. |
| ISL6262IRZ | Extended temperature grade (−40°C to 100°C vs. −10°C to 100°C); otherwise identical pinout, VID mapping, and IMVP-6 behavior. | Required for industrial or automotive-adjacent mobile applications operating below −10°C ambient; not qualified for extended cold storage or cold-start scenarios. | Choose ISL6262IRZ only when design must guarantee operation at −40°C; ISL6262CRZ-TK is sufficient for commercial-grade notebooks and tablets. |
Compared with ISL6262CRZ and ISL6262IRZ, the ISL6262CRZ-TK offers identical regulation performance and IMVP-6 compliance but is optimized for automated manufacturing-its tape-and-reel configuration ensures consistent pick-and-place placement and reduces line-stoppage risk in volume production.

FAQ
What is the operating temperature range for the ISL6262CRZ-TK?
The ISL6262CRZ-TK is rated for an ambient operating temperature range of −10°C to 100°C, with junction temperature up to 125°C. This range aligns with commercial-grade mobile computing applications and is validated per the FN9199 Rev 2.00 datasheet absolute maximum and recommended operating conditions.
Does the ISL6262CRZ-TK support both DCR and resistive current sensing?
Yes, the ISL6262CRZ-TK supports both lossless inductor DCR current sensing-with built-in NTC thermistor compensation-and precision resistive current sensing using external shunt resistors. Both methods feed into the VSUM node and are fully compatible with the device's droop amplifier and overcurrent protection circuitry.
How does the R3 Technology™ in the ISL6262CRZ-TK improve transient response?
The R3 Technology™ modulator in the ISL6262CRZ-TK synthesizes clean analogs of inductor ripple current and uses them in hysteretic comparators-enabling variable switching frequency during load transients. This delivers faster voltage recovery (<10 µs) than fixed-frequency PWM while retaining 0.5% DC accuracy via its integrated error amplifier.
What is the purpose of the VR_TT# pin on the ISL6262CRZ-TK?
The VR_TT# pin on the ISL6262CRZ-TK is an open-drain thermal overload indicator output. When the internal NTC-based thermal monitor detects die temperature exceeding the threshold (VNTC falling below 1.18 V), VR_TT# pulls low with ≤9 Ω resistance-signaling host logic to initiate thermal throttling or shutdown before permanent damage occurs.
Can the ISL6262CRZ-TK operate with only one phase enabled?
Yes, the ISL6262CRZ-TK automatically enables single-phase operation when PSI# is asserted low, transitioning smoothly from two-phase CCM to one-phase CCM. At lighter loads, it further enters one-phase discontinuous conduction mode (DCM) upon DPRSLPVR assertion-maximizing efficiency without external control.
