AMD SVI2移动CPU内核电源用双输出PWM控制器

RT3662AM是集成了3组MOSFET驱动器的双输出PWM控制器，它符合AMD SVI2电压调节器规范，可为CPU内核和北桥部分供电。它采用定电流纹波固定导通时间(Constant Current Ripple Constant On-Time, CCRCOT）及立錡专有的G-NAVP控制架构，易于设定以满足AMD AVP(Adaptive Voltage Positioning)的需求，简单设定误差放大器的直流增益即可获得所需电压随载下降的参数。借助适当的补偿，负载瞬态响应特性也能对AVP性能进行优化。它还能通过相互之间的接口发送VOTF完成信号，将VDD/VDDNB电压和电流数据编码以后 • 2/1相（VDD）+1/0相（VDDNB） PWM控制器\n• 集成2组MOSFET驱动器\n• G-NAVP™控制架构\n• 支持动态负载线和0负载线\n• 轻载二极管仿真模式\n• SVI2接口，兼容AMD电源管理协议\n• 电流增益可调\n• DVID加强\n• 0.5% DAC 精度\n• 远程差分电压检测\n• 集成ADC实现参数设定、温度指示和输出电压、电流申报\n• 快速瞬态响应\n• Power Good指示\n• 温度指示\n• OVP/UVP/UVLO\n• 过流保护;
