Other Parts Discussed in Thread: UCC12050
My customer test the UCC12404 with ISO-EVM, and used 10K to pull high to active the gate driver,
In this state, they found that the upper left corner of the IC thermally rises by 70C when the ambient temperature is 28C with no load and full load of 90mA/3.3V.
Is this status normal? thanks.
You can find the setup in the following pic.
