Other Parts Discussed in Thread: LM5165,
We have sold over 1400 Devices with the LM5165 and no problems with it (we have 3 units on board so 4200 units LM5165).
Now, due to procurement problems, we have currently switched to the LM5166 because it is compatible and does his job.
However, after more than 400 other devices with the LM5166 (3x400 = 1200), many complaints have come back.
After a more detailed analysis, we also came to the conclusion that the LM5166 has an internal defect that causes it to switch off after quick changes to the FB Pin and does not start working again without restarting via Vin or the EN Pin.
Since I found at least 3 further entries in this forum with the same Problem but unfortunately without a solution, I want to know whether there are any unofficial solutions?
Because everyone went offline.
I mean in more detail the following 3:
LM5166: Supply ramdomly shuts down, does not restart - silicon fault?
LM5166: Turn off and doesn't come back without powercycle
LM5166: Part turns off and does'nt come back without powercycle
Thanks for your help
