500Khz clock, LM319 as comp/error amp and a TC4420 as output stage with output filter. Or same comb with UCD technologie if you prefered...Really easy!

Replace the TC4420 by a pair of PNP/NPN follower and that's done!

Thank you fredos. I actually need some overshoot current solvers in my design. I have completed most of the design but I have to deal with overshoot current and some volume, gain control and effects. Could you help me about this subjects?
