Hello!
I'm trying to build a switching power supply but the schematic doesn't seem to do the work, at the output I got the same voltage as at the input.
The 5K trimmer doesn't have any effect, for D1 I use UF5408 and for D2 1N5819.
R1 is 0,22 Ohm.
I've uploaded the schematic. Could you tell me if is something wrong with the circuit?
