10w class D amplifier design

yasar262 · 8th February 2010, 12:22 PM

Hi guys,
I need some schematics for a 10 W class D amplifier for my project. Could anyone help me please?

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!

do we have another design just for education only, that can be simulate to electronic workbench simulator.

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?
