I went on digikey looking for a cheap SEPIC switching regulator and found this:
http://search.digikey.com/us/en/products/SC4503TSKTRT/SC4503TSKCT-ND/1249536
I'm confused because the datasheet describes itself as a boost regulator... but also a SEPIC regulator. Aren't SEPICs both boost and buck in one? Why would it only advertise itself as a boost regulator then? Near the bottom of the datasheet, it shows a single SEPIC application: a Li-ion cell (2.6-4.2V) to a steady 3.3V. So I think this regulator is good for my needs.
I have a 5V source and need to produce a 3.3V, 5V, or 13V output using the same regulator (but not at the same time). None of the output voltages will source very much current (less than 100ma). Any reason that regulator wouldn't work for me?
Thanks.
