TPS51200 用于DDR4 VTT端接,测量上电时序时发现DDR_VTT上电时有回沟,同时造成为TPS51200的其他电源也产生了回沟。

Other Parts Discussed in Thread: TPS51200

TPS51200 用于DDR4 VTT端接,测量上电时序时发现DDR_VTT上电时有回沟,同时造成为TPS51200的其他电源也产生了回沟。【测量波形中CH2=DDR_IO;CH3=DDR_VTT;CH4=DDR_VPP;】个人觉得可能是因为TPS51200的Soft-start时间太快造成inrush current太大把前前级电源拉得不稳定。请问有办法调整Soft-start的时间长短么。
