Benefits:
  • 8-phase dual output PWM Controller
  • Phases are flexibly assigned between Loops 1 and 2
  • Intel® VR12, AMD® 3.4MHz SVI/PVI and Memory modes
  • Overclocking and Gaming Mode with Vmax setting
  • Switching frequency from 200kHz to 1.2MHz per phase
  • IR Efficiency Shaping Features including Variable Gate Drive and Dynamic Phase Control
  • Programmable 1-phase or 2-phase for Light Loads and Active Diode Emulation for Very Light Loads
  • IR Adaptive Transient Algorithm (ATA) on both loops minimizes output bulk capacitors and system cost
  • Auto-Phase Detection with auto-compensation
  • Per-Loop Fault Protection: OVP, UVP, OCP, OTP, CFP
  • I2C/SMBus/PMBus system interface for telemetry of Temperature, Voltage, Current and Power for both loops
