TLV62084A: Ripple voltage of PWM and PFM

Part Number: TLV62084A

Hello,

My customer has a question about TLV62084A.

Is the ripple voltage lower at PFM than at PWM?

They compare Figure 11 and Figure 12 in the data sheet.
In Figure 12 (PFM), the ripple voltage is lower.

Could you confirm it?

Thank you.

  • Hi Mayumi,

    yes, for the particular application case where those curves are obtained and showed on the datasheet, PFM and PWM ripples are comparable. By the way this is not a general rule that you can apply to every operation condition and passives combination. You should evaluate your specific case.
