If the ripple current exceeds the capacitor’s rating, it can cause overheating and failure. Check the capacitor’s datasheet for its ripple current rating and ensure it is suitable for your application.

Conclusion:

Output capacitance failure in the MPQ8633BGLE-Z can be caused by improper capacitor selection, damaged components, or poor circuit design. By following the diagnostic steps outlined above, you can quickly identify the cause of the issue and replace the faulty components with suitable replacements. Proper capacitor selection, correct placement, and a well-designed circuit layout will ensure stable operation and reliable performance of your power management system.
