    Hey all need a tiny project quick. I am needing to turn my 48v POE lines to an output of 5v and around 3.5a. Also on the same PCB I would like that 48v to also output 28v and around 1a. Putting both on the same PCB will cut the cost of making them. Only one output will be used depending on what needs to be powered. Both voltages will not be used at the same time. There also will need to be one so...
