Hello ! Yes, I used the components that the Datasheet says, I got it from here:
The thing is, that a Triple Voltage Circuit uses electrolitic capacitors, this is not the same configuration as a voltage triple circuit, but, Can It be that the capacitors I added are not electrolitic? I just putted normal ones (SMD 10nF 250V). Thanks a Lot! El miércoles, 24 de junio de 2020, 14:49:49 (UTC+2), Paul Andrews escribió: > > Read the layout recommendations in the LT1308A datasheet.
