Part Number: LMR43620-Q1 Tool/software: Hi team,
My customer want to do 5V output simulation. But seeing from product page, there is only 3.3V output simulation model.
Can you provide 5V model or teach me how to do if there is not 5V model.

Part Number: LMR43620-Q1 Tool/software: Hi team,
My customer want to check their inductance selection. Here is their calculation.
And they want to use inductor which have 20% variation. So the worst case is;
2.75uH > 3.3uHx0.8 = 2.64uH
2.75uH < 4…
