Hi
I'm having some problem with the TPS60500 on my final design for a project I'm doing. I have a supply voltage of roughly 4.9V which
I want to convert to approx. 3.3V and I've set the voltage divider correctly. But for some reason I get an output voltage of 4.39V and 0V
at the FB pin for some reason. I'm using the reference design for the project and all values except the voltage divider has been changed.
The whole solution should work because I've verified it once with a test board which gave me exactly the right voltages (3.27V on Vout and
0.8V on FB) but for some reason it's not working for my larger design. Is there a possibility that the chip got destroyed when soldering it even
though it looks fine. Or is there some way to find out what has gone wrong?
Hope someone can help me
Best regards
Pontus
