TPS62160: Non-systematic Errors in Regulation of Output

Part Number: TPS62160

Hello, 

I've been having various issues in line and load regulation on of my designs. The issues are inconsistent between PCBs and can vary by the day on the same PCB. I've attached a word document with a summary of some of the issues we are seeing along with schematic, layout, bom, and oscope captures. Any guidance would be much appreciated, thank you.

  • Bryce,

    The input cap C11 should be after the ferrite bead FB1. You will need to change the layout accordingly too. Let us know if that helps resolve the issues. Also, it would be good to refer to layout example Fig. 42 on page 26 mentioned on page  in the datasheet.

    Regards,
