DESCRIPTION
 6-phase & 8-phase dual output PWM Controller
 Phases are flexibly assigned between Loops 1 & 2
 Intel® VR12, AMD® 3.4MHz SVI/PVI & Memory modes
 Overclocking & 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
