Hi,
I am trying to use TPS63021DSJR for converting a litium battery (between 2.5V, 4.2V) to 3.3V and also 5V (while charging the battery) to 3.3V. But i am getting 6.3V output. I could not find why. Here is my schematic and pcb.

Dear user:
Have you checked the soldering? I afraid the feedback resistance maybe not soldering well.
Dear User:
I just realize that you are using the fixed Vout version. Please short the FB pin to the Vout directly.
