I have to build a Switch Mode Power Supply with multiple outputs. I've seen many projects with just a single output , as well as projects with variable voltage output, such as using an lm317. However, I'm unsure as to whether the variable voltage output is the same as multiple voltage outputs - though logically it is very different. So, here are the basics of where I am with my project so far and how I would like to move forward:
The SMPS has to output three voltages: 12V. 5V and 3.3V. In this respect I've researched flyback converters. I would like to know how well these work. I have checked out this site which comes closest to what I need (I think) -
https://www.digikey.com/reference-designs/en/ac-dc-and-dc-dc-conversion/ac-dc-smps-multi-output/36
I have not decided yet whether to step down from mains (220VAC) or from DC batteries. If DC is chosen, will the battery power have to be well above (12+5+3.3)V?
These are all the questions I have for now. Thanks!
