LMR62014 in SEPIC configuration

Other Parts Discussed in Thread: LMR62014, LM3481

Hello,

I would like to use the LMR62014 with a SEPIC configuration.

Vin = 4.5V to 5.5V,

Vout will be adjusted from 3.5V to 8 V (using digital potentiometer).

Iout max = 0.2A

Is it possible?

Yes you can use it in that configuration. Let me dig up a schematic.

Couldn't find a schematic for the LMr part, but here is an example of a higher current sepic design using the LM3481.
