I want to incorporate a switching power supply that can supply 5V at around 5A in a project. I know how to make simple linear power supply but I have never designed a switching power supply that can supply high current.
What do I need to know (tutorials?) thats different from regular linear power supplies? Does the transformer current rating have to be equal or more than 5A to make a 5A regulated DC supply? I looked up some high current transformers and they are expensive, but I see switching power supplies on ebay selling for around 20 bucks, so am I missing something about the size of the transformered needed?
General information needed here.
Thanks.
