TPS53125

Low voltage power rail for dual-channel synchronous buck controller

illustrate

 

该TPS53125是一款双通道，自适应开启时间的D - CAP2模式同步降压控制器。 该器件使系统工程师可以低成本有效地完成了很少的外部元件数量和低待机消费的各种终端设备的稳压电源总线套件。 为TPS53125主控制循环使用的D - CAP2模式拓扑结构，提供了一个非常快的瞬态响应，无需外部元件。

该TPS53125还具有专用电路，使装置不仅适应低等效串联电阻（ESR）的输出电容，如POSCAP /遣散-上限，但也陶瓷电容。 该器件提供了从4.5转换方便，高效的运作电压V至24 V，而输出电压从0。
