IR3570AMIE04TRP Description

The IR3570AMIE04TRP is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation and is fully compliant with AMD? SVI1 & SVI2 and Intel? VR12 specifications. The IR3570AMIE04TRP includes IR’s Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR’s Dynamic Phase Control adds/drops active phases based upon load current and can be configured to enter 1-phase operation and diode emulation mode automatically or by command.

IR3570AMIE04TRP Features

Dual output 4+1 and 3+2 phase PWM Controllers

Easiest layout and fewest pins in the industry

Fully supports AMD? SVI1 & SVI2 with dual OCP and Intel? VR12

Overclocking & Gaming Mode

Switching frequency from 200kHz to 2MHz per phase

IR Efficiency Shaping Features including Dynamic Phase Control and Automatic Power State Switching

Programmable 1-phase operation for Light Loads and Active Diode Emulation for Very Light Loads
