Product details
Overview
ISL62883BHRTZ from Renesas (formerly Intersil) is a 3-phase PWM buck controller IC for Intel IMVP-6.5™ mobile CPU core power delivery, featuring Robust Ripple Regulator (R3™) modulator technology, 0.5% system voltage accuracy over temperature, -10°C to +100°C operating range, and integrated dual gate drivers with external third-phase support. It enables precision multiphase regulation in notebook computers.
For engineers reviewing the ISL62883BHRTZ datasheet, ISL62883BHRTZ pinout, ISL62883BHRTZ application, or ISL62883BHRTZ equivalent, key selection criteria include IMVP-6.5™ compliance, programmable 1-/2-/3-phase operation, differential remote sensing, DCR/resistor current sensing, and adaptive body diode conduction time reduction in diode emulation mode.
Technical Context
The ISL62883BHRTZ implements a multiphase R3™ modulator architecture that combines fixed-frequency PWM stability with hysteretic-like transient response-achieving variable switching frequency during load transients while reducing frequency at light load to improve efficiency. It supports PSI# and DPRSLPVR signals to dynamically add/drop phases and adjust overcurrent thresholds.
It uses differential remote voltage sensing (VSEN/RTN) for die-level regulation, supports lossless inductor DCR or discrete resistor current sensing with NTC thermal compensation, and features an adaptive body diode conduction time reduction function to minimize conduction loss in diode emulation mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiphase CPU core regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL62883HRTZ | Same functionality and electrical specs, but in 40-lead 5×5 mm TQFN (L40.5x5); θJA = 32°C/W vs. 29°C/W for ISL62883BHRTZ | Lower thermal performance margin; suitable only where board space is more constrained than thermal headroom | Select ISL62883HRTZ only if layout requires smaller footprint and thermal derating is acceptable |
| RTQ2136B-QA | 3-phase IMVP-8.0 controller with integrated MOSFET drivers, higher integration, and automotive AEC-Q100 Grade 2 qualification | Targets newer CPU generations and automotive infotainment; lacks IMVP-6.5™ PSI#/DPRSLPVR protocol support | Choose RTQ2136B-QA only for new IMVP-8.0 designs or automotive-grade requirements-not a drop-in replacement |
Compared with ISL62883HRTZ, the ISL62883BHRTZ offers lower thermal resistance (29°C/W vs. 32°C/W) and larger package area for improved heat spreading, while RTQ2136B-QA provides next-generation protocol support and AEC-Q100 qualification-but neither replicates the exact IMVP-6.5™ feature set, phase-shedding logic, or VID timing behavior of ISL62883BHRTZ.

FAQ
What is the operating temperature range for the ISL62883BHRTZ?
The ISL62883BHRTZ is specified for an ambient operating temperature range of -10°C to +100°C, with a maximum junction temperature of +125°C. This range is explicitly defined in the FN6891 datasheet ordering information table for the ISL62883BHRTZ variant and aligns with its intended use in commercial notebook applications.
How does the ISL62883BHRTZ differ from the ISL62883HRTZ?
The ISL62883BHRTZ and ISL62883HRTZ share identical functional specifications and IMVP-6.5™ compliance, but differ in package: ISL62883BHRTZ uses a 48-lead 6×6 mm TQFN (θJA = 29°C/W), while ISL62883HRTZ uses a 40-lead 5×5 mm TQFN (θJA = 32°C/W). The larger package improves thermal performance for sustained high-current operation.
Does the ISL62883BHRTZ support both DCR and resistor-based current sensing?
Yes, the ISL62883BHRTZ supports both lossless inductor DCR sensing and precision discrete resistor current sensing. It includes dedicated ISEN pins for each phase and allows thermal compensation of DCR drift using a single NTC thermistor connected to the NTC pin-validated in the FN6891 datasheet Sections 1.2 and 3.3.
What is the purpose of the ISEN3/FB2 pin on the ISL62883BHRTZ?
The ISEN3/FB2 pin on the ISL62883BHRTZ serves a dual function: in 3-phase mode, it acts as ISEN3 for phase-3 current sensing; in 2-phase mode, it becomes FB2-a secondary feedback node used to optimize compensation for 1-phase operation. This flexibility eliminates the need for hardware changes when reconfiguring phase count.
Is the ISL62883BHRTZ RoHS compliant and lead-free?
Yes, the ISL62883BHRTZ is Pb-free and RoHS compliant, as confirmed in the FN6891 datasheet "Features" section and "Ordering Information" table. It uses 100% matte tin (e3) termination finish and meets IPC/JEDEC J-STD-020 moisture sensitivity level requirements for lead-free reflow.
