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: 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…
Hi Yaman,
For the single phase designs, both need increased output capacitance to be stable. I am using the quickstart calculator to estimate 60 degrees of phase margin with 330uF of output capacitance.
The dual phase design is unstable. The compensation…
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,…
Hi Mark,
I'm not sure why WEBENCH isn't selecting FETs. The LM5146 is a 100V rated device, so 100V FETs should be fine.
If you can fill out the LM5146 quickstart calculator, I can review your design and recommend some FETs.

Hi Zhang,
Thanks for using the e2e forum. Could you provide me the datasheet of the inductor?
Could you also fill in our quickstart calculator tool for this LM3488 design? https://www.ti.com/tool/download/LM3478-88-BOOST-CALC
Based on this information, we…
Hello,
Go ahead and complete the quickstart calculator file so we can review component selection, power losses and stability.
