IR3570BMTRPBF Description

Short technical summary and product information.

The IR3570BMTRPBF from Vishay Dale is a dual loop digital multi-phase buck controller. It offers dual output 4+1 and 3+2 phase PWM control, supporting AMD SVI1 & SVI2 and Intel VR12 & VR12.5 specifications. This controller operates with a +3.3V supply voltage and is designed for ambient temperatures ranging from -40°C to 85°C.

 

Key features include a switching frequency from 200kHz to 2MHz per phase, IR Efficiency Shaping Technology, and Adaptive Transient Algorithm (ATA) to minimize output bulk capacitors. It provides per-loop fault protection including OVP, UVP, OCP, and OTP. The device includes an I2C/SMBus/PMBus system interface for telemetry of temperature, voltage, current, and power for both loops.

 

The IR3570BMTRPBF is available in a 5x5mm, 40-pin QFN package with a 0.4mm pitch. It is offered in Tape and Reel packaging with 3000 units or in Tray packaging with 4900 units. The component is Pb-Free and Halogen Free.
