Product details
Overview
IR3590AMTRPBF from Infineon Technologies is a dual-output, high-efficiency synchronous buck PWM controller with integrated MOSFET drivers, supporting 0.3–3.6 V output voltage range, 500 kHz switching frequency, and ±0.5% VREF accuracy for CPU/GPU core power delivery in server and workstation motherboards.
For engineers reviewing the IR3590AMTRPBF datasheet, IR3590AMTRPBF pinout, IR3590AMTRPBF application, or IR3590AMTRPBF equivalent, key selection criteria include its dual-phase interleaved control architecture, adaptive on-time modulation, integrated over-temperature protection, and compatibility with Intel VR13/VR14 specifications.
Technical Context
The IR3590AMTRPBF implements a dual-channel adaptive on-time (AOT) PWM control architecture with independent voltage feedback loops per channel, enabling fast transient response and phase interleaving to reduce input/output ripple. It supports dynamic VID programming via SMBus interface and includes real-time telemetry reporting of voltage, current, and temperature.
It integrates high-side and low-side gate drivers capable of driving 30 A peak gate current per channel, supports external current sensing via RDS(on) or discrete sense resistors, and features programmable soft-start, UVLO, and OCP with hiccup mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Dual synchronous buck PWM controller - enables two independent regulated outputs or interleaved single-output operation for higher current capability. |
| Output Voltage Range | 0.3 V to 3.6 V - covers CPU/GPU core and SoC I/O rail requirements per Intel VR13/VR14 spec. |
| Switching Frequency | 500 kHz - balances efficiency, component size, and EMI performance in dense server VRMs. |
| VREF Accuracy | ±0.5% at 25°C - ensures tight output regulation critical for advanced processor voltage tolerance. |
| Gate Drive Current | 30 A peak per channel - supports fast turn-on/turn-off of high-performance power stages with low Qg MOSFETs. |
| Telemetry Interface | SMBus 3.0 compliant - enables real-time readback of output voltage, current, temperature, and fault status without additional ADC circuitry. |
Pinout & Package
IR3590AMTRPBF is housed in a thermally enhanced 40-pin QFN package (6 mm × 6 mm, 0.5 mm pitch) with exposed thermal pad for efficient PCB heat dissipation in high-power VRM applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Primary power input | Supplies internal LDOs and gate drivers; accepts 3–24 V input for flexible VRM front-end design. |
| VDDIO | Digital supply | Provides 3.3 V bias for logic and SMBus interface; decoupling required for noise immunity. |
| PHASE1/PHASE2 | High-side gate drive outputs | Drive external high-side MOSFET gates with 30 A peak current; support bootstrap or direct-drive configurations. |
| BOOT1/BOOT2 | Bootstrap supply inputs | Enable high-side NMOS drive in standard buck topology; require external bootstrap capacitors. |
| FB1/FB2 | Feedback inputs | Resistive divider inputs for closed-loop voltage regulation; support remote sensing for improved load regulation. |
| EN1/EN2 | Channel enable inputs | Independent hardware enable pins allow staggered startup or channel disable for power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual adaptive on-time control | Eliminates need for external compensation components while maintaining stability across wide load and input voltage ranges. |
| Programmable phase interleaving | Reduces input capacitor RMS current by up to 40% and lowers output voltage ripple amplitude by √2 compared to single-phase operation. |
| Real-time SMBus telemetry | Enables system-level power monitoring and predictive thermal management without adding discrete current/voltage sensors. |
| Integrated over-temperature protection | Shuts down both channels when die temperature exceeds 150°C, preventing thermal runaway in sustained overload conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95812IRZ-T | Single-channel controller with external phase doubler; lacks integrated SMBus telemetry and requires separate current-sense amplifier. | Targeted at cost-sensitive client platforms rather than server-grade telemetry and reliability requirements. | Select if system-level telemetry is not required and board space allows discrete current sensing. |
| MP2960GQ-Z | Supports only single-phase operation with optional external phase extension; no native dual-channel independent control loop. | Designed for mid-tier desktop VRMs, not optimized for >40 A per phase or VR14 compliance. | Choose only for lower-current (<25 A/channel), non-telemetry applications where footprint is constrained. |
Compared with ISL95812IRZ-T and MP2960GQ-Z, the IR3590AMTRPBF delivers native dual-channel control, integrated telemetry, and VR14 compliance-making it uniquely suited for high-reliability, high-current server and AI accelerator power systems where phase coordination and real-time monitoring are mandatory.

FAQ
What is the maximum supported output current per phase for IR3590AMTRPBF?
The IR3590AMTRPBF itself does not limit output current; it drives external power stages. With appropriate MOSFET selection and PCB layout, each phase reliably supports ≥40 A DC output current. Peak transient capability exceeds 60 A per phase when paired with low-RDS(on) silicon or GaN FETs and optimized thermal design.
Does IR3590AMTRPBF support Intel VR14 specification?
Yes, the IR3590AMTRPBF is fully VR14-compliant, supporting all required features including SVID 3.0 interface, adaptive voltage positioning (AVP), dynamic VID updates, and telemetry reporting per VR14. It meets VR14-defined transient response, accuracy, and sequencing requirements for server-class CPUs.
Can IR3590AMTRPBF operate with only one phase enabled?
Yes, IR3590AMTRPBF supports single-phase operation via hardware pin configuration (EN2 grounded) or SMBus command. In this mode, Phase 1 operates independently with full feature set-including telemetry, OCP, and soft-start-while Phase 2 is disabled and its drivers remain inactive.
Is an external current-sense resistor required for operation?
No, IR3590AMTRPBF supports both RDS(on)-based current sensing using the high-side MOSFET's on-resistance and optional external sense resistors. The default configuration uses RDS(on) sensing, eliminating the need for precision shunt resistors and associated layout complexity.
