Hi, Team

Are there recommended value ?

FB Resistor value are R1 124kΩ, R2 100Ω .

Hi Nakamura-san,

I think you mean a Cff (feedforward cap)?

This app note, found on the product page, discusses exactly this topic: www.ti.com/.../slva466a.pdf

If there is a specific load transient requirement, please share it.
