TPS54426: Recommended Component Values including DC biasing effect?

Takashi Onawa

Part Number: TPS54426

Hi Team,

My customer want to know if they need to take care DC biasing effect for Recommended Component Values indicated in Table1.

Is those value shows nominal value? or effective value? If it means nominal value, they need to choose larger cap against Table1.

Those look like nominal capacitance values. I could not find an effective value stated in the datasheet. On the EVM, effective value is around 35uF but this is for a 1.05V design. If you’d like me to recommend or review any specific caps for your design, please let me know.

Thanks,

Amod
