    Hi Mehdi,

    T1 is a common mode filter to help reduce EMI emission. Q1 is a bypass switch that will conduct if uses, when the LM5150 is not switching, to save the conduction losses in the inductor and rectifier diode. I will be turned of by the LM5150 when boost operation starts.

    Thanks,
    Youhao
