My customer now use TPS61071 so as to convert 4V to 5V.
Customer now haven't added load. And found that the output and FB is very strange.
The Vin and Enable are ok.
Customer have made several board, and each board have different Vo and FB, such as Vo and FB are only 0-3V...
Could you please help to check whether their SCH or PCB are correct or not?
in SCH, C46=4.7uF abd C51=10uF.
