Hello,
Customer is using TPS65251 and measured Gain/Phase on their board.
Unusual phase curve is observed when Ta=-40 deg. C and Iout=1A. (Please see attached file.)
Customer separates the load circuit on the board and used electric load.
Customer uses all 3 channels and another channel have same trend.
Please advice how to investigate the reason of unusual phase curve.
