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…
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,…
Hello,
Please use the LM5145 quickstart calculator to help with compensation design for the LM5145 https://www.ti.com/tool/LM5145DESIGN-CALC .
Also, the various transfer functions (Vout-to-COMP and COMP-to-Vout) are provided in the datasheet.
Regards…
Parker,
Go ahead and fill out the quickstart calculator and I will review it for each design. See the apps circuit examples in the datasheet for reference. Btw, the LM5137-Q1 is online now.

HI Naveen,
can you share all design parameters used for Webench.
You can also use the Quickstart Calculator:
https://www.ti.com/tool/download/LM5118QUICK-CALC
It allows you a better control and access to the parameters.
Best regards,

Hi Hideyuki,
the result are close to the actual design as most of the parameters are considered.
You can also use the quickstart calculator which allows you to adjust more parameters.

That FET has a very high Qrr of 111nC - try one with lower Qrr to improve the noise behavior, e.g. CSD18563Q5A.
