So, i am 80% done with redrawing ludo's PCB for this SMPS, only have to add the fast diodes and capacitors. The protection card PCB is completely redrawn, and i'm planning to fit it on the main PCB because it will be simpler to make it (one PCB instead of two). Only problem is i have to shorten the protection PCB for 20mm as it is now 32x80mm and then it will fit, i'll move some elements around for the best fit. I won't share the .brd file, i will only give the pdf version.
For now i won't draw any other versions, as in my mind this is the simplest design for the PCB (great job ludo3232
), if i do another design, i'll post here.
And two questions:
1. Where on the schematic do the 'current sense' leads from the PCB in the attachment hook up to?
2. What is the use of the jumper connected to the 1uF capacitor and one lead from the ETD49 transformer? Is it necessary for something, or can i draw the PCB without it?
Edit: sorry for small thumbnail, but you all have the schematic, so no problem
