PSA: Chipamp.com snubberized PSU schematic with part numbers
1 Attachment(s)
Hi everyone:
I've received so much help from you all on my Chipamp project, that I thought I'd make an (albeit small) contribution back. Here is a pic. of the Chipamp.com PSU with part numbers on top, as well as the LED power light indicator circuit and parts. Hope this helps someone. |
As has been pointed out in the past, the polarity of C6 is shown the wrong way round.
|
Actually, confusingly, it's the lower bridge that is reversed

I'm a total newbie with nearly zero electronics knowledge. If you would please clarify what you mean by that, I will try to fix the diagram. |
Reverse D3,4,7&8
|
scottjoplin:
Sorry, not clear. What do you mean by reverse? Do you mean swap label D3 with D8 and swap D7 with D4 or something completely different? |
Look at the two halves of the PSU - the same connections that give positive output on top give a negative output on the bottom :D
Leave C6 and the other components as they are, but connect the D3/D7-node to the negative side of C6 and the D4/D8-node to the positive side. /U. |

I can't really imagine in my mind exactly how that would look. Maybe someone else can change the diagram and re-post? |
Current only flows in one direction through a diode. Some of the diodes are drawn the wrong way and need to be reversed. This schematic keeps popping up with the same response.
|
The problem is only with the circuit diagram. The Chipamp power supply PCB is correct.
