Hi Team,
My customer now use LM5175 to output 12V.
When Vin=12V,which means Vin=Vout, customer found that output is pulled down (nearly 0V) and Inductance has abnormal noise.
When Vin improved to 17V, the output is normal.
May I ask when Vin=Vout, how will LM5175 adjust? Why Inductance has abnormal noise?
Here are the SCH and PCB. SCH is almost the same as EVM and PCB has some difference.
