Hi,

Can you please provide the tool regarding the compensation network.

See the below image for reference from MPN - TPS54160. I want the same tool for MPN - TPS54561-Q1

    Hi Ajay,

    Unfortunately TPS54561-Q1 does not have a calculator excel tool ready to use from the website, however there are some alternate solutions. There is a Webench tool and simulation available to use for TPS54561-Q1 that can provide component values you can use along with the values in the datasheet. As a secondary alternative the TPS54x40_and_TPS54x60_Buck_Design_Spreadsheet can be modified to calculate estimated values for the TPS54561 by providing the following values from the datasheet on the data page of the calculator. The equations used in the calculator match the ones used in TPS54561 except for RT, and are similar for the RCOMP value but not exact. You will need to manually compute RT from the TPS54561-Q1 datasheet. I highly recommend you use the Webench tool first before modifying the calculator tool as it has been custom made for TPS54561-Q1.
