If the IC is going into thermal shutdown, reduce the system load or improve cooling. Replace the IC (If Needed): If all other solutions fail and the current draw remains excessive, consider replacing the ADP5052ACPZ-R7 IC, as it may be damaged or defective.Conclusion:
Excessive current draw in the ADP5052ACPZ-R7 is typically caused by a few key factors, including overloaded outputs, faulty components, incorrect layout, voltage irregularities, or thermal issues. By following the steps outlined above, you can systematically diagnose and resolve the issue. Always ensure that your load, components, and input conditions are within the specified limits for the IC, and ensure proper cooling to avoid thermal problems. If these steps don't resolve the issue, the IC may need to be replaced.
