the ph signal wave form ,those drop will cause my output ripple becames bigger,I don't know the reason.
TPS5430 is fixed frequecy 500khz,is this dc go into DCM mode?

Hello,
I have calculated that inductor current ripple is 0.8A. What is your Io? if Io <0.5 *0.8A, then converter will go to DCM.
Thanks
