RT8889D Description
The RT8889D is a three phase CPU power controller with triple integrated drivers for VR12.5 pliant. The RT8889D adopts G-NAVPTM (Green Native AVP) which is Richtek's proprietary topology derived from finite DC gain of EA amplifier with current mode control, making it an easy setting the droop to meet all Intel CPU requirements of AVP (Adaptive Voltage Positioning). Based on the GNAVPTM topology, the RT8889D also.
