Tool/software: WEBENCH® Design Tools
Hello,
I am interested in the step-down converter LM5165.
That's why I used the Excel Tool "LM5165 Wide Vin Low Iq Buck Converter Quickstart Design Tool.xlsm" and the Online WEBENCH Designer.
But the efficiency charts are quite different (with (nearly) the same parameters and component values).
Why are there such big differences (e.g. Iout = 80mA> 78% and 87%, 10mA> 56% and 85%)?
Am I doing something wrong ?
with best regards
Markus
