We have a problem with part of 1173080 (UCC28631 FLYBACK)
CONTR) Component is mounted on ICCPD (position N4)
Flyback does not work.
Details are given in the test report:
The main voltages like 13V, 6.5V and -13V are not generated. The Flyback doesn’t work.
Start-Up voltage for N4 is reached, but there is no output signal on Pin 5 (DRV) for switching the main transistor V19. The voltage on this pin remains 0V.
Failure – The output stage doesn’t generate any signal.
After replace of N4 for new one, the ICCPD was working again.
the defect part N4 was detected.
