TPS92515HV: frequency of input voltage ripple

Ryuji
Guru 20090 points
Part Number: TPS92515HV

Hello

In the datasheet P.31 , there is the description of  "The input ripple must go no higher than 10% of the input voltage to a maximum of 2 V".
Could you please let me know the frequency range of this input voltage requirement?

I think that the low frequency input voltage change is acceptable.

Best Regards,

    Hello Ryuji,

    The ripple that statement refers to is at the switching frequency of the device. That is the frequency you need to design for 10% or 2V or less. Low frequency line transients/changes of greater than 10% or 2V are perfectly fine and the device will adjust to them and regulate well.

    Regards,
