TPS54620: Resr & Iout values look up to be applied on TPS54620

Part Number: TPS54620

Hi,

i'm browsing through the following document & thinking of applying same methodology on TPS54620 hence I would like to know Resr for the output capacitor (47µF) and Iout used to generate Figures 64 and 67 of this document.

https://www.ti.com/seclit/ml/slup084/slup084.pdf

Please advise on how can i look up for these information. Thanks.

Regards,

Leo

    Leo,
    The document you reference regarding RHP zeros is not applicable to buck converters such as TPS54620. Also the highest figure number in the datasheet is Figure 57. If you mean Figures 34 and 35, that 47 uf output capacitor is a ceramic type. You can use 0.003 ohm as the ESR.
