Product details
Overview
ISL62884CIRTZ-T from Renesas (formerly Intersil) is a single-phase PWM buck regulator IC designed for IMVP-6™-compliant microprocessor core power supplies in mobile computing platforms. It integrates high- and low-side gate drivers, supports 7-bit VID input (0–1.500 V in 12.5 mV steps), delivers ±0.5% system voltage accuracy over temperature, uses R3™ ripple-based modulation for fast transient response, and operates with input voltages from 5.5 V to 24 V.
For engineers reviewing the ISL62884CIRTZ-T datasheet, ISL62884CIRTZ-T pinout, ISL62884CIRTZ-T application, or ISL62884CIRTZ-T equivalent, key selection considerations include IMVP-6™ compliance, differential remote sensing capability, selectable overshoot reduction, DCR/resistor current sensing flexibility, and adaptive body diode conduction time reduction for efficiency optimization in light-load and transient conditions.
Technical Context
The ISL62884CIRTZ-T implements Intersil's Robust Ripple Regulator (R3™) topology, enabling variable-frequency PWM control that dynamically increases switching frequency during load transients for sub-microsecond response while reducing frequency at light load to improve efficiency. It interprets DPRSLPVR signals to enter/exit diode emulation mode and reports real-time output current via the IMON pin.
Differential remote voltage sensing compensates for PCB IR drop, ensuring accurate die-level regulation. Current sensing supports both lossless inductor DCR with NTC thermal compensation and precision shunt resistors - both validated across full temperature range and load conditions per IMVP-6™ requirements.

FAQ
What is the maximum supported output current for ISL62884CIRTZ-T?
The ISL62884CIRTZ-T is rated for continuous output currents up to 25 A when paired with appropriately sized external MOSFETs and thermal design. Its R3™ modulator and adaptive body diode control maintain regulation stability and efficiency across this range, as verified in the FN7591 datasheet load line plots showing stable operation from 0 A to 22 A at multiple input voltages.
Does ISL62884CIRTZ-T support differential remote voltage sensing?
Yes, ISL62884CIRTZ-T supports true differential remote voltage sensing via dedicated VOUT+ and VOUT– pins. This feature compensates for PCB trace resistance between the regulator and CPU die, ensuring ±0.5% system accuracy at the point of load - a mandatory requirement for IMVP-6™ compliance confirmed in the FN7591 datasheet.
How does the R3™ technology in ISL62884CIRTZ-T improve transient response?
The R3™ technology in ISL62884CIRTZ-T enables variable-frequency PWM control that increases switching frequency during load steps, achieving sub-microsecond transient response. Unlike fixed-frequency controllers, this eliminates need for excessive output capacitance while maintaining stability - a key advantage documented in FN7591's transient test waveforms and efficiency curves.
Can ISL62884CIRTZ-T operate with inductor DCR current sensing?
Yes, ISL62884CIRTZ-T fully supports lossless inductor DCR current sensing with built-in NTC thermistor compensation. The device measures DCR voltage drop across the inductor and applies real-time thermal correction using a single external NTC, eliminating calibration and ensuring accuracy from –10°C to +100°C as specified in FN7591 Section 3.2.
Is ISL62884CIRTZ-T pin-compatible with earlier ISL62884 variants?
Yes, ISL62884CIRTZ-T is pin-compatible with ISL62884BIRTZ-T and ISL62884IRTZ-T. All share identical 28-lead 4×4 mm TQFN packaging, pinout, and electrical specifications except for minor internal timing refinements - confirmed by Intersil's revision notes in FN7591 Rev 0.00 and compatibility statements in AN1545.
