I'm needing a dual-output IC that will step up a 3.7V lithium battery to 5V (6V if possible) @ 2A and 12V @ 200mA. I'm trying to power a small vibrating motor rated at 5-6V and a small clock that requires 12V. I've found several ICs that will do either 5V or 12V (such as the MC34063A), but I'm having trouble finding a dual output in a single package. Most of the dual-output chips I'm finding are pretty low current. The 12V output doesn't need a lot of current, but more is definitely better for the 5V output since it is driving the motor. I feel like I'm asking for someone to Google things for me, but perhaps my DigiKey/Mouser filter skills are sub-par because I'm having trouble finding something that fits the bill.

Thanks a lot!

 

You're better using converter modules ready made, select the output type you need and current rating, get it from a supplier in your country.

Yeah, I was actually looking for pre-made modules if possible, so your response is perfect. However, yikes - I can't find any that aren't super expensive (like $25+)! Maybe I'm missing something? Perhaps I should stick to separate ICs/boards for each voltage...
