IR3581MTRPBF Description

Short technical summary and product information.

The IR3581MTRPBF from Vishay Dale is a dual-loop digital multi-phase buck controller, compliant with Intel VR12 and VR12.5 specifications. It is designed for CPU voltage regulation, servers, and high-performance graphics processors.

 

This controller features a programmable switching frequency per phase, ranging from 194kHz to 2MHz, with 56 steps for fine-tuning. It operates on a nominal 3.3V supply voltage and is rated for an ambient operating temperature range of -40°C to 85°C.

 

The IR3581MTRPBF incorporates IR's Efficiency Shaping Technology, including Variable Gate Drive and Dynamic Phase Control, to optimize efficiency across various load conditions. It supports programmable 1-phase or 2-phase operation for light loads and active diode emulation for very light loads. The device also includes IR's Adaptive Transient Algorithm (ATA) to minimize output bulk capacitors and system cost.

 

Packaged in a 48-pin QFN (6mm x 6mm) with a 0.4mm pitch, this surface-mount component is supplied on tape and reel in standard quantities of 3000 units. It offers I2C/SMBus/PMBus system interface capabilities for telemetry reporting.
