RT8130C 是 5V/12V 供电的单相同步 Buck 控制器,采用 Green Voltage Mode(GVM™)控制架构,可在轻载条件下自动进入二极管仿真模式,并以固定导通时间的 PFM 模式降低开关切换频率,从而达成提升转换效率的效果。当负载电流增加以后,即退出二极管仿真模式而进入固定频率的 PWM 模式而工作在连续导通状态。其集成化的 MOSFET 驱动器具有高驱动能力,支持高达 12V 的驱动以满足大电流应用的需要。它采用无损耗的下桥 MOSFET RDS(ON) 电流检测技术实现过流保护,其保护阈值可通过 LGATE 引脚进行设定(LGOCS)。此外,它还具有 Power Good 指示、使能/禁止控制和内部的软启动设计,具有完整的保护功能对功率级进行保护,是具有极高性价比的高效电源转换器件,其封装为 WDFN-10L 3x3。
