Hi,

I want to know the effiency of LM5001 for SEPIC configuration.

I have heard that an efficiency generally becomes small by a SEPIC circuit .

How bad does it become ?

When there is a effiency graph, I'm happy.

thanks.

Hi,
The efficiency really depends on the application conditions and the design. There is reference design using LM5001 as a SEPIC converter, and you find the efficiency curve in the test report (http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=tidu552&fileType=pdf), which might give you an idea about the efficiency.
Thanks.
