Product details
Overview
IR3086MTRPBF from Infineon Technologies is a dual-phase synchronous buck controller IC designed for high-efficiency VRM/VRD-compliant CPU power delivery. It supports 4.5–24 V input, delivers up to 120 A per phase with adaptive on-time control, and integrates MOSFET drivers for external N-channel FETs in server and desktop processor power stages.
For engineers reviewing the IR3086MTRPBF datasheet, IR3086MTRPBF pinout, IR3086MTRPBF application, or IR3086MTRPBF equivalent, key selection criteria include its 2-phase interleaved operation, programmable switching frequency (200–1200 kHz), integrated over-temperature protection, and compatibility with Intel VRD12/VRD13 specifications.
Technical Context
The IR3086MTRPBF implements adaptive on-time (AOT) control architecture with automatic dead-time optimization and cycle-by-cycle current limiting. It features independent voltage feedback loops per phase, differential remote sensing inputs, and a dedicated PSi pin for power-state interface signaling to CPU VRM controllers.
It supports dynamic VID voltage programming via 7-bit digital interface compliant with Intel VRD12.0/13.0 standards, includes internal 5 V LDO for gate driver bias, and provides fault reporting through PROCHOT# and PGOOD outputs with adjustable delay timing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6367IRZ-T | Uses PWM control instead of adaptive on-time; requires external compensation network. | Lacks native VRD13 support; limited to VRD11.1 and earlier CPU generations. | Preferred where legacy platform compatibility or fixed-frequency EMI requirements dominate. |
| MP8765GQ-Z | Single-chip 2-phase controller with integrated high-side/low-side FETs; no external driver needed. | Lower max current (70 A per phase); not suitable for >100 A CPU core rails. | Selected for space-constrained designs where integration outweighs current scalability needs. |
Compared with ISL6367IRZ-T and MP8765GQ-Z, IR3086MTRPBF offers superior transient response via AOT control, full VRD13 compliance, and higher per-phase current capability-making it optimal for next-generation server and high-end desktop CPU power stages.

FAQ
What is the recommended gate driver configuration for IR3086MTRPBF?
The IR3086MTRPBF drives external N-channel MOSFETs using integrated 2 A peak gate drivers per phase. Each phase requires a bootstrap capacitor (typically 0.1 µF ceramic) between BOOTx and PHASEx, and low-inductance gate resistors (1–5 Ω) to control slew rate and minimize ringing. External FETs must be rated ≥30 V VDS and optimized for high-frequency synchronous operation.
Does IR3086MTRPBF support phase shedding?
Yes, IR3086MTRPBF supports automatic phase shedding via its PSi pin interface, which accepts CPU power-state signals (PS0–PS4). When PS3 or PS4 is asserted, the controller disables one phase to reduce quiescent current and improve light-load efficiency, while maintaining regulation on the active phase.
Can IR3086MTRPBF operate with a single-phase configuration?
No, IR3086MTRPBF is strictly a dual-phase controller and requires both phases to be populated and configured. It does not support single-phase operation or phase disable via configuration pins-both PHASE1 and PHASE2 connections must be implemented with matched external FETs and inductors.
What thermal management considerations apply to the 28-MLPQ package?
The 28-MLPQ package features an exposed thermal pad that must be soldered to a minimum 200 mm² copper pour on the PCB's inner layer with ≥6 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). Junction-to-board thermal resistance is 22°C/W; board-level airflow ≥200 LFM reduces steady-state die temperature by up to 15°C under full load.
