Hi,


I have a custom design of ADP5052 Adjustable version.  According to ADP5052 datasheet, FB1, FB2,FB3, FB4 are 0.8V, FB5 is 0.5V.


But in my design I saw that  FB1, FB2,FB3,FB4 are 0.85V and FB5 is 0.55V.  Thats why all output voltages are wrong. What can be reason of that?




Thank you




Regards
