Dear TI Experts
I am now using TPS54225,12V to 5V,2A
When power on, the output voltage is 9V and then be pulled down immediately~
we have done many experiments: changed the Inductor 、add output Capacitance、use DC power supply, but nothing makes sense, Can you give me any suggestions ?Thank you very much~
Here is the output wave and the SCH(the same as wenbench)
