    Hi  Kim,

    Uh, you asked same questions for TPS63060, right?

    Behavior of TPS63070 is similar with TPS63060, so you can take the answer in TPS63060 thread as ref.

    Regards

    The TPS63070 datasheet does not mention Burst mode. Please confirm if TPS63070 has Burst mode or Pulse Skip mode in Power Saving mode or in Forced PWM mode.

    Hi

    For every device in PFM, burst or pulse skip mode always exist when load is light.

    in FPWM mode, there is no burst or pulse skip mode.

    Regards
