Hi Lee,
I suggest taking a look at the following reference design. This implements the LM5155 (similar to the LM5156) as an uncoupled SEPIC controller with a positive and a negative output voltage. This design can be easily changed to meet the application…
Hi A.S.
I have a few ideas for the power supply. I think a good solution would be to use the LM5155 in a dual SEPIC configuration similar to

However the power level of that particular design is not close to what you need…
Hello,
Sepic can be used in your application.
I recommend looking at this thread for more information on designing a SEPIC converter.

Sorry for the delay because I just came back from a business trip.
Like mentioned, this can be done with the LM5155 in a SEPIC configuration. We do have a dual output SEPIC to generate +/- dual output rails (link below). You can use the same topology…
Part Number: LM5155 Hello,
I am trying to use the LM5155 in a SEPIC configuration (12V to 24V @ 3A).
Webench does not allow for SEPIC designs with this part, so I made a boost design, exported it to TINA, and then built my own SEPIC in TINA.
To avoid…
Part Number: LM5022 Other Parts Discussed in Thread: LM5155 , TIDA-020009 Team,
I have seen the below LM5022 TI design for a BUCK/BOOST based on SEPIC: http://www.ti.com/tool/PMP40488
-Are we planning any SEPIC TI design based on LM5155? -What would be the…
