<div align="justify">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-NAVP<sup>TM</sup> (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-NAVP<sup>TM</sup> 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 rates : Fast, Slow and Decay. By utilizing the G-NAVP<sup>TM</sup> topology, the operating frequency of the RT8876A varies with VID, load and input voltage to further enhance the efficiency even in CCM. The built-in high accuracy DAC converts the SVID code ranging from 0.25V to 1.52V with 5mV per step. The RT8876A integrates a high accuracy ADC for platform setting functions, such as no-load offset or over current level.</div>
