Product Overview

IR35204MTRPBF is a 3+1 dual output digital multi-phase controller. It is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation, and is fully compliant with Intel®, VR12 Rev 1.7, VR12.5 Rev 1.5, IMVP82 Rev 1.2, and AMD SVI2 REV 1.06 specifications. The IR35204 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 phases based upon load current. The IR35204 can be configured to enter 1 or 2-phase PS1 operation and active diode emulation mode automatically or by command. IR's unique adaptive transient algorithm (ATA), based on proprietary non-linear digital PWM algorithms, minimizes output bulk capacitors. Applications include Intel® VR12, VR12.5 and IMVP8 (overclocking only), AMD SVI2 based systems, servers and high end desktop CPU VRs, high performance graphics processors, memory VR.
  • Ultra-low quiescent power dual output 3+1 phase PWM controller
  • Switching frequency from 194KHz to 2MHz per phase in 56 steps
  • IR efficiency shaping features including dynamic phase control and automatic power state switching
  • Programmable 1 or 2-phase operation for light loads and active diode emulation for very light loads
  • IR Adaptive Transient Algorithm on both loops minimizes output bulk capacitors and system cost
  • Auto-phase detection with PID coefficient autoscaling
  • Fault protection OVP, UVP, OCP, OTP, CAT-FLT
  • I2C/SMBus/PMBus interface for reporting of temp, voltage, current & power telemetry for both loops
  • Multiple time programming with integrated charge pump for easy non-volatile programming
  • 40-pin QFN 5 package
