RT8884C 是支援 4/3/2/1 相操作的多相同步 Buck 控制器，具有串列 VID 介面，符合 Intel VR12.5 相容 CPU 的需要。它採用立錡專有的基於有限直流增益誤差放大器的電流模式控制技術的 G-NAVP<sup>TM</sup> 架構，壓降特性易於設定，符合 Intel CPU 的 AVP(adaptive Voltage Positioning) 需求，同時具有面對瞬變負載時的快速回應特性以優化其 AVP 性能。它支援不同操作狀態下的模式轉換功能，具有內建的串列 VID (SVID) 介面與 Intel VR12.5 相容的 CPU 進行通訊，可以快、慢和自然過渡三種不同的速率支援 VID 動態變換。由於具有 G-NAVP<sup>TM</sup> 架構，RT8884C 的工作頻率可以隨著 VID、負載電流和輸入電壓而變化，即使在 CCM 模式下，其效率也能得到最大想讀的提升。此外，CCRCOT 技術則在整個輸入、輸出範圍內提供了極低的輸出電壓漣波。
