RT3674AE 是完全满足 AMD CPU/GPU SVI3 电源需求的三输出同步 Buck 控制器，它采用立锜专有的使用有限直流增益误差放大器的电流模式控制的 G-NAVP™ (Green Native AVP) 架构，易于设定输出电压随载下降幅度以满足 AMD CPU/GPU 对 AVP（Adaptive Voltage positioning，自适应电压定位）的需求，在负载瞬变和输出电容减少的情况下有全新的 AQR (Adaptive Quick Response，自适应快速响应）快速响应机制提供优化了的 AVP 性能。它集成有用于状态上报的高精度 ADC 和用于存储客户配置信息的非易失存储器，可对输出电流幅度、自动相数增减阈值、工作频率、过流限制阈值和 AQR 触发阈值等进行设定。它还具有完备的保护性功能设计，其中包括过压保护、欠压保护、过流保护和欠压闭锁等。RT3674AE 给各个输出轨提供了独立的使能、Power Good 和温度检测，也支持通过 I<sup>2</sup>C 接口对许多功能进行设定。
