    Hi linjie,

    Transient models does not support bode plot simulations. You would need an average  PISPICE model for that.

    Unfortunately, we could not find an average model for this device.

    You could use the Excel calculation tool of TPS61022 or WEBENCH power designer tool below to get the bode plot.

    Best regards

    Hi, Sneha   

    Thank you for your quickly reply. I have find the bode plot by the Excel calculation tool of TPS61022 or WEBENCH power designer tool.

    It seams that most of dc/dc ICs don't have average  PISPICE model on web of TI.
