Tool/software: WEBENCH® Design Tools
Hello together,
today I used the TI Webench to design an switchting regulator. The frame conditions are: V_in=10...50 V, V_out=3.3 V and I_out=2 A. Webench proposed me to use the LM46002 if I want to have also a good efficiency under low current conditions. In the following I plotted the charts for efficiency (log-scale) and efficiency, but I don't understand why I get a minima on the left chart @0.27 A, that doesn't occure on the right chart.
Has anyone an idea why I get this result? In my opinion, it can only be a mistake in the calculation of the diagrams or an inaccuracy occurring there.
Thanks for your help and sorry for my bad English
Max
