Product details
Overview
ISL62883BHRTZ-T from Renesas Electronics (formerly Intersil) is a 3-phase PWM buck controller IC for Intel IMVP-6.5™ mobile CPU core power delivery. It integrates two gate drivers, supports DCR/resistor current sensing, delivers ±0.5% system voltage accuracy over temperature, and enables diode emulation mode for light-load efficiency. It is used in high-performance notebook CPU VRMs.
For engineers reviewing the ISL62883BHRTZ-T datasheet, ISL62883BHRTZ-T pinout, ISL62883BHRTZ-T application, or ISL62883BHRTZ-T equivalent, key selection considerations include IMVP-6.5™ compliance, programmable 1-/2-/3-phase operation, R3™ modulator transient response, differential remote sensing, and thermal compensation via NTC.
Technical Context
The ISL62883BHRTZ-T implements Intel IMVP-6.5™ protocol with support for PSI# and DPRSLPVR signals to dynamically add/drop phases (PWM3, Phase-2) and adjust overcurrent thresholds. It uses Robust Ripple Regulator (R3™) technology, combining variable-frequency response during transients with fixed-frequency stability at steady state.
It provides differential remote voltage sensing (VSEN/RTN), adaptive body diode conduction time reduction in diode emulation mode, and user-selectable overshoot reduction. Current sensing is configurable via inductor DCR (with NTC thermal compensation) or discrete resistors, and output current reporting is available on the IMON pin.
Key Specifications

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-T | Same functionality but in 40-lead 5×5 mm TQFN; lacks ISEN3/FB2 pin and third phase capability | Restricted to 1- or 2-phase designs; not suitable for full 3-phase IMVP-6.5™ implementations requiring Phase-3 control | Select ISL62883HRTZ-T only if board space is constrained and 3-phase operation is unnecessary |
| RTQ2136B-QA | 3-phase controller with integrated MOSFET drivers and PMBus interface; supports Intel VR13/VR13.0 specifications, not IMVP-6.5™ | Designed for newer CPU generations; lacks native PSI#/DPRSLPVR support and IMON analog reporting | Choose RTQ2136B-QA for VR13-compliant platforms; avoid for legacy IMVP-6.5™ systems requiring exact protocol timing and signaling |
Compared with ISL62883HRTZ-T and RTQ2136B-QA, the ISL62883BHRTZ-T uniquely supports full 3-phase IMVP-6.5™ operation with dedicated ISEN3, FB2 flexibility, and backward-compatible logic thresholds - making it the only option for validated notebook designs requiring all three phases and legacy CPU compatibility.

FAQ
What is the operating temperature range for the ISL62883BHRTZ-T?
The ISL62883BHRTZ-T is specified for an ambient operating temperature range of -10°C to +100°C, with a maximum junction temperature of +125°C. Its thermal resistance is θJA = 29°C/W and θJC = 2°C/W in the 48-lead TQFN package, enabling reliable operation in thermally dense notebook VRM layouts when properly heatsinked via the exposed GND pad.
Does the ISL62883BHRTZ-T support both DCR and resistor-based current sensing?
Yes, the ISL62883BHRTZ-T supports both lossless inductor DCR current sensing-with thermal compensation via a single NTC thermistor on the NTC pin-and precision discrete resistor current sensing. The choice is configured externally via circuit topology; DCR sensing eliminates power loss in sense elements, while resistor sensing offers higher signal-to-noise ratio in noisy environments.
How does the R3™ modulator in the ISL62883BHRTZ-T improve transient response?
The R3™ modulator in the ISL62883BHRTZ-T improves transient response by dynamically increasing switching frequency during load steps-via COMP voltage rise accelerating master clock generation-while maintaining 0.5% DC accuracy through its integrated error amplifier. This achieves faster voltage recovery than fixed-frequency PWM and greater noise immunity than pure hysteretic control.
What is the purpose of the FB2 pin on the ISL62883BHRTZ-T?
The FB2 pin on the ISL62883BHRTZ-T serves dual functions: in 3-phase mode, it acts as ISEN3 for Phase-3 current sensing; in 2-phase mode, it becomes FB2-a dedicated compensation node that optimizes loop stability and transient performance when operating in 1-phase fallback mode, using external RC components connected to FB2 and FB.
Can the ISL62883BHRTZ-T be used in a 1-phase configuration?
Yes, the ISL62883BHRTZ-T is fully programmable for 1-, 2-, or 3-phase operation. In 1-phase mode, it disables PWM3 and Phase-2 via internal logic, configures ISEN3/FB2 as FB2 for optimized compensation, and scales overcurrent protection thresholds accordingly-enabling flexible design reuse across different CPU TDP classes without changing the ISL62883BHRTZ-T footprint.
