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,
You can use the LM25143-Q1 42V input version of the controller here. As it's a controller, the applicable application space is quite broad.
My recommendation is to use the quickstart calculator to assist with your design: https://www.ti.com…
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.

Hi Robin,
thank you for supporting the LM5175.
Could you please attach the filled out LM5175QUICKSTART-CALC to this thread?
This will give the best overview on the application setup and requirement.
Can you also add some more details on the conditions: …
Depends on if you need two phases. If you only need one phase, then the LM5148 is an option (and this is stackable to two phases if needed).
Typically, we only need two phases if the output current exceeds 20-30A (depending on Vin-max, Fsw, max ambient…
Hi Neo,
I suspect the design is unstable - please complete the quickstart calculator to check https://www.ti.com/tool/LM5145DESIGN-CALC . Note the 22uF/25V output cap will be ~10uF at 8VDC. Set the crossover < 25kHz. what is the ESR of the electrolytic…
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.
