Overview
® RT8876A Dual Channel PWM Controller with 3/2/1 Phase for CORE VR and Single Phase for AXG VR General Description The RT8876A is a VR12/IMVP7 compliant CPU power controller which includes two channels : a 3/2/1 phase with 3 integrated drivers synchronous Buck controller for the CORE VR, and a single phase Buck controller for the AXG VR.
The RT8876A adopts G-NAVPTM (Green Native Adaptive Voltage Positioning), which is Richtek's proprietary topology derived from a finite DC gain compensator with current mode control, making it an easy setting PWM controller, meeting all Intel CPU requirements of AVP.
Based on the G-NAVPTM topology, the RT8876A also features a quick response mechanism for optimizing AVP performance during load transient.
The RT8876A supports mode transition function with various operating states.
A serial VID (SVID) interface is built in the RT8876A to communicate with Intel VR12/IMVP7 compliant CPU.
The RT8876A supports VID on-the-fly function with three different slew...
