Tool/software: WEBENCH® Design Tools
1) I have an eval board and I have swapped out some components loosely in accordance with web bench for 48 in 24v 5 amps out. It works ok when loaded up but when un loaded the output bounces up and down and seems to be going in to soft start. In my application I have over 6000uF on the output, this is necessary. I think the circuit behaves worse with the extra capacitance.
2) on the eval board there is R6 and C20, but not on the webench circuit. I can guess what they do, but should i fit them to my layout (still in progress)?
