Infineon Technologies IR3584MTRPBF Multi-Phase PWM Controller
The IR3584MTRPBF from Infineon Technologies is a high-performance, multi-phase PWM controller designed for precision voltage regulation in advanced computing and power delivery systems. This 32-pin QFN-packaged IC supports input voltages from 4.5V to 21V and enables multi-phase configurations (up to 8 phases) for high-current applications, delivering output voltages as low as 0.5V with exceptional accuracy (±0.5% voltage reference). Operating at a programmable switching frequency up to 1.5MHz, it ensures efficient power conversion across industrial temperature ranges (-40°C to +125°C). The device integrates adaptive timing control, phase shedding, and dynamic voltage scaling (DVS) for optimal efficiency under varying loads.
Key Features
The IR3584MTRPBF excels with its adaptive phase-balancing technology, which minimizes current imbalance between phases for reduced thermal stress. It features a digital interface for real-time configuration of voltage, frequency, and fault thresholds, alongside integrated MOSFET drivers with 3A peak current capability. Advanced protection mechanisms include over-current, over-voltage, under-voltage lockout (UVLO), and thermal shutdown. The controller also supports spread-spectrum modulation to reduce EMI and complies with VR12/12.5/13 specifications for CPU/GPU power applications.
Applications
This controller is optimized for high-current DC/DC converters in servers, data center equipment, AI/ML accelerators, and high-end GPUs. Its multi-phase architecture suits VRM (Voltage Regulator Module) designs for CPUs, FPGAs, and ASICs requiring ultra-low ripple and fast transient response. Additional applications include telecom infrastructure, industrial automation systems, and high-density power supplies for 5G base stations or autonomous vehicle computing platforms.

Usage Considerations
Implement a symmetrical PCB layout with matched trace lengths for phase nodes and current-sensing paths to maintain balance. Use high-quality X7R/X2Y decoupling capacitors near the VCC and driver pins to suppress noise. Ensure proper heatsinking for power-stage components, as controller efficiency depends on external MOSFET thermal performance. Avoid exceeding 21V input or 1.5MHz switching frequency to prevent instability. Calibrate current-sensing networks using Infineon’s recommended precision resistors (±1% tolerance), and enable phase shedding during light loads to maximize system-level efficiency. Always validate thermal derating curves for target operating environments.
