RT8179B 是双输出的 PWM 控制器，符合AMD SVI2 电压调节器规范，可以同时为 CPU 内核（VDD）和其北桥部分（VDDNB）供电。它采用立锜专有的 G-NAVP(Green-Native AVP) 技术和 CCRCOT（Constant Current Ripple Constant On-Time，固定电流涟波固定导通时间）控制拓扑，易于设定、控制，可满足 AMD AVP(Adaptive Voltage Positioning) VDD/VDDNB 的所有要求。其压降特性可通过对误差放大器的直流增益进行设定而实现；使用适当的补偿设计，符合 AVP 性能要求的瞬态响应特性也很容易获得；通过双方之间的控制接口，控制器也可很容易地将 VOTF 完成信息、VDD 和 VDDNB 的电压、电流编码信息传递给 CPU；它可以进入二极管仿真模式，从而确保在各种负载条件下都可实现高达90%的效率；通过适当的埠设定，它可根据特殊的需要进行偏移量设定。它提供 Power Good 指示、过流指示（OCP_L）和分别针对内核和北桥的双重过流保护机制，还具有完善的保护功能如过压、欠压和负压保护等。
