Hello support,
I tried to replicate the "DEMO_5QR0680AZ_42W1" board with some minor modifications. Attached I send the schematic.
The difference is the feedback loop, where the 5V output is only controlled.
I did a production of 300 boards, and half of the boards, the chip ICE5QR0680AZ is in a state that tries to start, and after a while, sometimes it starts and sometimes it doesn't!
Am I doing something wrong? Do I have a feedback loop, calculated wrong?


Best regards
Ivo Bernardo
