Hello,

Currently trying to use boost power management device, LM51571-Q1 with an input voltage of 24V and boosting to 26V.  We have the following circuit:

However, we are observing a 1-1.2V ripple on the output.  What recommendations might TI suggest for improving output noise ripple shown in plots

    Hi Omar,

    Thanks for reaching out.

    For what output current is this boost converter designed?

    When you see the shown behavior, are you operating in low load condition?

    It would also be good to see the bahavior of the switchnode, input voltage and Comp pin in parallel to the output voltage.

    I am looking forward for your response.

    Best regards

    Moritz
