Description | The RT8889D is a three phase CPU power controller with triple integrated drivers for VR12.5 compliant. The RT8889D adopts G-NAVPTM (Green Native AVP) which is Richtek's proprietary topology derived fr... |
Features |
a quick response mechanism for optimized AVP performance during load transient. The RT8889D supports mode transition function with various operating states. A Serial VID (SVID) interface is built in the RT8889D to communicate with Intel VR12.5 compliant CPU. The RT8889D supports VID on-the-fly function with three different slew rates : Fast, Slow and Decay. By utilizing the G-NAVPTM topology, the operating frequency of the RT8889D varies with VID, load current and input voltage to further enhance the efficiency even in CCM. Besides G-NAVPTM, the CCRCOT (Constant Current Ripple Constant On Time... |
