RT2776是一款與VR12/ IMVP-7相容的CPU電源控制器,它包括兩個通道:一是用於CORE VR、具有三個整合的驅動器的3/2/1相位同步降壓控制器,另一是用於AXG VR、單相位降壓控制器。RT2776採用G-NAVP™(綠色原生自我調整電壓定位),是立錡專有的架構,來自有電流模式控制的有限直流增益補償器,使其成為一個容易設置的PWM控制器,能滿足所有Intel CPU 對AVP的要求。基於G-NAVP™的架構,RT2776還有一個在負載瞬態時,快速回應機制的特性,以達到最佳的AVP性能。RT2776支援在各種操作狀態的模式轉換功能。內建於RT2776的串列式VID(SVID)介面與符合Intel VR12/ IMVP7的CPU進行通訊。RT2776支援VID上的即時功能與三種不同的電壓變動率 (slew rate):快,慢和衰減。藉用G-NAVP™架構,RT2776的工作頻率隨VID,負載和輸入電壓而變化,以進一步提高效率,即使是在CCM模式。內建高精確度DAC以5mV為一階,將SVID代碼轉換為從0.25V到1.52V的電壓。RT2776整合了高精確度ADC,作平臺設置之用,例如無負載偏移或過流保護值之設定。
