Hi Prasimix, hi kleinstein,
At the moment I use only one power mos.
the second one will only assembled if one mos is not enough to handle the power.
I use this ps with max of 10 amps.
Also I use at the moment only cv mode.
Iset is constant on 5 volts which is than the maximum.
I use 1,5 ampere load for testing.
So I will try several things in the next days. I decrease already c18 and c23 to 1 nf.
The sawtooth will not be there if I connect only one line, means c18 or c23. But than I get an pretty good oscillation when I connect a load.
I must thinking about that, what can be the next steps.
Cheers
Sven
