TPS62112 efficiency Vs inductor DC resistance

Q: TPS62112 efficiency Vs inductor DC resistance by 13270

Hello,

TPS62112 efficiency is dependant on the inductor DC resistance.

My customer plans to use TPS62112 & have selected an inductor with 300mohm DC resistance.

They would like to know the effect of higher DC resistance on efficiency. If we have a graph depicting efficiency Vs DC resistance, please share the same.

Also, give your comment regarding 300mohm DC resistance.

We do not have graphs of the efficiency versus DCR of the inductor but this app note, http://www.ti.com/lit/an/slva390/slva390.pdf, Switcher Pro, or evaluating the EVM will give you the information you require.
