Product details
Overview
ISL6262AIRZ-T from Intersil is a two-phase buck core voltage regulator implementing Intel® IMVP-6+ protocol with integrated 2A gate drivers, 7-bit VID DAC (0.300–1.500V), ±0.8% system accuracy over –40°C to +100°C, and R3 Technology™ for ultra-fast transient response in laptop CPU power delivery.
For engineers reviewing the ISL6262AIRZ-T datasheet, ISL6262AIRZ-T pinout, ISL6262AIRZ-T application, or ISL6262AIRZ-T equivalent, this page delivers verified technical context, validated pin functions, confirmed IMVP-6+ compliance, real-world efficiency curves at 2-phase/1-phase CCM and deeper-sleep modes, and precise current-sensing implementation options (DCR or resistive).
Technical Context
The ISL6262AIRZ-T employs R3 Technology™-a patented Robust Ripple Regulator modulator that synthesizes noise-free inductor ripple analogs and uses hysteretic comparators referenced to the error amplifier output, enabling variable switching frequency during load transients for fastest-in-class response. It supports dynamic phase adding/dropping via PSI# and DPRSLPVR signals to transition between 2-phase CCM, 1-phase CCM, and diode-emulation light-load mode.
It integrates dual 2A gate drivers with <8ns rise/fall times, differential remote sensing (VSEN/RTN), droop-based IMVP-6+ load-line regulation, and precision current monitoring via ISEN1/ISEN2 with static/dynamic sharing. Protection includes OV/UV/OC thresholds, thermal shutdown (VR_TT#), and PGOOD with 7.6ms delay.

FAQ
What is the operating temperature range for the ISL6262AIRZ-T?
The ISL6262AIRZ-T is rated for industrial temperature operation from –40°C to +100°C ambient, with junction temperature limits up to +125°C in active mode. This extended range ensures reliable performance in thermally demanding laptop chassis and ruggedized portable designs where internal board temperatures exceed commercial-grade limits.
Does the ISL6262AIRZ-T support both DCR and resistive current sensing?
Yes, the ISL6262AIRZ-T supports both lossless inductor DCR sensing-with built-in NTC thermal compensation-and precision resistive current sensing via ISEN1 and ISEN2 pins. The datasheet provides dedicated application circuits (Figures 32 and 33) and specifies matching tolerances for each method to ensure accurate current measurement and phase balancing.
How does the R3 Technology™ in the ISL6262AIRZ-T improve transient response?
R3 Technology™ in the ISL6262AIRZ-T synthesizes clean analog representations of inductor ripple current and applies them to hysteretic comparators referenced to the error amplifier output. During load transients, this causes immediate switching frequency increase-unlike fixed-frequency PWM-delivering faster voltage recovery and lower peak deviation, as validated in Figure 14 (35A step response).
What is the function of the PMON pin on the ISL6262AIRZ-T?
The PMON pin on the ISL6262AIRZ-T provides an analog voltage output proportional to the product of VSEN and the droop voltage (DROOP – VO), enabling real-time CPU power calculation. It sources/sinks up to 2mA and operates within 0.308–3.0V range, allowing direct connection to an external ADC for dynamic power management and thermal throttling decisions.
Can the ISL6262AIRZ-T be used in single-phase configurations?
Yes, the ISL6262AIRZ-T supports forced single-phase operation by pulling ISEN2 to 5V, which disables Phase 2 gate signals. It also automatically enters 1-phase CCM when PSI# is asserted, and transitions to diode-emulation mode in deeper-sleep states-enabling optimized efficiency across the full 0–50A load range without hardware modification.
