RT3663BR是符合AMD SVI2电压调节器规范、为CPU内核 (VDD) 和其北桥部分 (VDDNB) 供电的3相 + 2相PWM控制器，使用立锜专有的G-NAVP (Green-Native AVP) 和CCRCOT (Constant Current Ripple Constant On-Time) 控制技术，易于根据AMD的AVP (Adaptive Voltage Positioning) 规格需求进行设定以满足VDD/VDDNB的供电需要，其电压随载下降的幅度是通过对误差放大器的直流增益的设定来完成的。借助适当的补偿，负载瞬态回应的特性可以取得优化的AVP性能。该控制器可通过介面发出VOTF完成资讯、数位化编码了的VDD/VDDNB电压、电流资讯。它可以根据不同的负载条件进入单相工作模式和二极体模拟模式，使转换效率可以高达90%。它可以通过设定引脚提供特别的偏置能力，具有输出准备好信号输出、过流指示输出和双重过流保护机制，具有多种故障保护能力如过压保护、欠压保护和负压保护等。
