Part Number: LM27403
Hi TI expert,
We recently met an issue about bode plot test. The phase is abnormal when the load current is 3.5A and 7A from 1K-10K. We tried to adjust the zeros and poles. Still have not found a solution yet.
Has this issue been seen on LM27403 before? Please advise what may cause this.
