RT8884B 是支持 4/3/2/1 相操作的多相同步 Buck 控制器，具有串行 VID 接口，符合 Intel VR12.5 兼容 CPU 的需要。它采用立锜专有的基于有限直流增益误差放大器的电流模式控制技术的 G-NAVP<sup>TM</sup> 拓扑，压降特性易于设定，符合 Intel CPU 的 AVP(adaptive Voltage Positioning) 需求，同时具有面对瞬变负载时的快速响应特性以优化其 AVP 性能。它支持不同操作状态下的模式转换功能，具有内建的串行 VID (SVID) 接口与 Intel VR12.5 兼容的 CPU 进行通讯，可以快、慢和自然过渡三种不同的速率支持 VID 动态变换。由于具有 G-NAVP<sup>TM</sup> 拓扑，RT8884B 的工作频率可以随着 VID、负载电流和输入电压而变化，即使在 CCM 模式下，其效率也能得到最大想读的提升。此外，CCRCOT 技术则在整个输入、输出范围内提供了极低的输出电压纹波。
