TLVM13660: Design calculation tool

Egor Tamarin

Part Number: TLVM13660

I am designing a PDN based on the TLVM13660. On the TI website, I found a page referring to a calculation tool (https://www.ti.com/tool/TLVM136X0DESIGN-CALC), but on that page I cannot find a reference to the actual software.

Where could I download it? I am especially interested in tuning the CBOOT/RBOOT resistor for EMI performance and would like to run some simulations beforehand.

    Hello,

    The calculator tool is an excel spreadsheet that will help with designing the components to meet the datasheet recommendations.

    CBOOT should be set based on the recommended value in the datasheet. RBOOT is the resistor that can be tuned to slow down the SW rising slew rate which will help reduce the SW node ringing on the rising fast edge and improve EMI. The calculator tool does not have any simulation on this behavior. 

    I have contacted the web content manager to get more insight on why the download button for this calculator tool is missing.

    However this calculator tool would not provide much insight on RBOOT resistor tuning. As such I suggest taking the TLVM13660EVM, tune the RBOOT resistor to your satisfaction, and measure the SW node.

    Regards,
