Dear Sir/Madam:
I need some clarification on TPS54561-Q1. I am using it for converting 50V to 5V. As specified in the datasheet, the Sw node voltage should not exceed -0.6V.
Since my catch diode forward voltage is 0.582V@8A, and I am getting -0.9V steadily @ 1A load current during OFF time.What I can do to bring the negative voltage less than -0.6V.
My design gets almost over.I don not want to change IC.
Best Regards,
Jenny
