Part Number: TPS60400-Q1

Dear team,

In our datasheet, there is one parameter named VACeff as below, but there is no definition about this. Could you please tell me what does that mean?

Thanks & Best Regards,

Sherry

    Hi Sherry,

    VACeff stands for the peak to peak AC voltage ripple. The capacitor in the LC filter is used to smooth the ripple but the ripple creates the AC current and results in power dissipation.
