Tool/software:
Hi,
UCC28C40 was tested at a high temperature of 70 degrees Celsius, and when outputting a load of 1A, the output voltage was too high. The designed output voltage of the product was 5.05V, with a 1% accuracy. However, during the test, there were unqualified products with an output voltage of 5.12-5.15V, and the accuracy of the output voltage could not be achieved. Could you please help analyze the reason?
Thanks!
