Dear Professors:
LM5069 overcurrent MOS damage. would you like to help explaining it?
LM5069 CTIMER pin was not found in test flow into protection mode (8 cycles a interval restart), the use of scenario is 10 Mr Sampling resistance, flow point at about 6 a (SENSE and VIN pin with 51 r resistance).If the sampling resistance is changed to 50mR resistor, the over-current point is around 1A, and the CTIMER protection mode is consistent with the specification (the interval of 8 cycles is restarted).
