Hi,
I'm currently looking for DC-DC converter circuit to supply my preamp (+/- 15V) and I found this 2 products on the market. The chip on the board is XL6009 and from the datasheet I found that it's probably done using SEPIC topology.
The board with small inductors rated for 8W max, while the other one with big inductor are rated for 20W max. I have a very minimum knowledge on how DC converter works and the only major differences I found from the picture is just the size of the inductors..
My question is : to increase the output current of the SEPIC topology, is it just as simple to increase the inductor current handling capabilities?
Thanks,
Salwa

Yes correct, that's XL6007.. both 6007 & 6009 use the same schematic for SEPIC topology on the datasheet.
And here's another module using XL6007 that I've been using recently on my preamp with decent result. I think the circuit on this module is simplified version from the datasheet, based on this youtube videos :
