    since this is basically in boost converter configuration am I correct in considering that this graph is correct? (from boost converter wiki)

    I also found this definition

    for that equation to work though I have to have Lpri which at this point is an unknown.

    how the heck do I solve this then?

    nevermind figured it out...

    D=1/((5/24)(3)+1)=.615
    DT=15.4uS
    DC=15.4uS/25uS=.615
