isolated buck converter
Hi. I am designing a forward converter. i am studying the circuit in this link. (page 9)

The circuit must provide 5V DC beteen 0-4A. The literature about SMPS suggests to use continuous mode. But, to supply 5V without reload or with big reload (e.g 20ohm) requires to jump discontinuous mode. Because designing such a big coil is impossible. I am not sure about choosing proper LC filter. Because there will be two different calculations for two different modes. (LC filter and feed back cicuit as well) What do you suggest about the beginning of the calculations? [/img]
