Tool/software:
Hi
We have the following issue with the controller of our speed pedelec, after it being used for over a year without any issues, we now start seeing with some bikes that while people bike the TPS54560-Q1 explodes. We use the TPS54560-Q1 3 times, 2 times to get 12V and once for 5V, but we only ever have this issue with the 5V conversion. Our system works on a 48V battery and controls two motors, the 5V is used to feed some sensors and the RPI controlling the system.
I already did a load test, put shorts on the output and even shorted the diode, trying to recreate this issue, but still no luck.
So I think my main questions are:
- Why is it only the 5V system experiencing this issue?
- What am I overlooking, is it possible that the motor frequencies that cause the input to fluctuate cause issues?
- Any more tests that I can do to try and recreate the issue in a controlled manner?
Kind regards
Midas
