If anyone is facing an issue with this.
The following are the reasons for IC getting damaged.
1.) As the feedback pin is high impedance. If the divider circuit used is of the value above 400K. There are chances that during production testing or assembly if by mistake the tester adds his/her impedance in the path. There will be a huge variation on the switching node and it may damage the output pin.
2.) If the Input voltage is by chance getting of its maximum value, it will damage the output of the chipset. In this case, even input gets damage as well.
Other than this there is no chance of getting the chipset output to fail. Failure in the IC won't be observed based on too high output capacitance or input capacitance.
We had a failure in IC because of an external interface getting with the 5V input under abnormal circumstances, this led to IC damage.
