TPS53667: Load Line - Intentional droop - Motivation

Darren Jenkins

Part Number: TPS53667

Team,

For a customer working with the TPS53667, can you explain more about the motivation behind setting a V-droop? Section 7.3.4 of the datasheet describes the setting. The customer would like to understand more about the purpose.

Thanks,

Darren

Hi Darren,

You can refer to the apps note below and find equation 11.

To have non-zero loadline design, overshoot performance can be improved and save output capacitors.

Thanks
