IR35211 Datasheet Dual Output Digital Multi-phase Controller

Manufacturer: International Rectifier (now Infineon)

Overview:   Dual Output Digital Multi-Phase Controller IR35211.

General Description

The IR35211 is a dual loop digital multi-phase buck controller designed for CPU voltage regulation and is fully compliant to AMD® SVI1 & SVI2 Rev 1.2 & Intel© VR12 Rev 1.5 PWM specification and VR12.5 Rev 1.3 PWM specification.

The IR35211 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.

Key Features

  • Dual output 3+1 phase PWM Controller.
  • Easiest layout and fewest pins in the industry.
  • Fully supports AMD® SVI1 & SVI2 with dual OCP and Intel® VR12 & VR12.5.
  • 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.
  • IR Adaptive Transient Algo.
