Part Number: LM5017-QUICKSTART-CALC Other Parts Discussed in Thread: LM5017 Is it possible some error in calculating Vout in the spreadsheet has gone undetected? Sometimes, the col for Vout will be wrong and in white so one cannot correct that.
An interesting…
Part Number: LM5145 Other Parts Discussed in Thread: , LM25145 , LM5146 Hi,
On the LM5145 product page both tools are listed. The Excel sheet looks similar, same input boxes. But when filling the sheets with the same requirements and values, I get large…
Correct link for the quickstart is: https://www.ti.com/tool/LM5145DESIGN-CALC .
Is the core loss super high for this inductor? High FET Qg at 500kHz?

Hello Chahak
I would recommend you using quickstart for the device to ease the design process. You can find it here - LM5116-5116WG-25116DESIGN-CALC Calculation tool | TI.com L et me know if you have any further questions or need clarification
Thank you …
Hi Joseph,
Thanks for using the e2e forum. There is a quickstart calculator available for LM5122-Q1. It can be found on the product page under "design & development" material. https://www.ti.com/tool/download/LM5122-BOOST-CALC

Part Number: LM5143DESIGN-CALC Other Parts Discussed in Thread: LM5143-Q1 Hi, Team,
Please let me confirm about "Effiency/Power Loss Analyzer shown in IM5143-Q1 Quickstart Design Tool. In the section of "Effiency/Power Loss Analyzer" in the file,…
Based on the Rth of the IC, about 1W is the highest you'd want to go. You can use an external VCC (8-13V) to reduce power dissipation, e.g. from a 12V output.
PS: use this quickstart file that covers the whole family https://www.ti.com/tool/LM5145DESIGN…
Hello Jacob,
What problem are you trying to solve? You should find the formulas for calculating the external components in the datasheet or you can use the quickstart calculator to get the right values: LM5171-CALC Calculation tool | TI.com
Best regards…
Thanks, Taylor. Send on the completed quickstart file - that's the key to determining losses, stability, etc. Also send the layout (screenshots are fine).

Hi Maggie
Thanks for sharing the schematic!
My first suggestion for the user to try compensation values suggested by the QuickStart and see if it improves the behavior. You can find QuickStart here - LM2557X-557XQUICK-CALC Calculation tool | TI.com . …
