Because people avoid zipped files because of viruses. So, here it is zipped, in the attachment. |

Does it work ok? Could you please send me the Eagle files (I have Eagle 7.7.0) and the LTSpice files? I 'll send you a pm with my email. EDIT: I tried but you have blocked PMs? --- End quote --- Sorry, I don't use a simulator. The design has been thoroughly tested by the thread's opening poster. I had built a bench supply with almost identical design which works perfectly well, https://www.eevblog.com/forum/projects/linear-lab-power-supply/375/. But I prefer the other design as it has better Under-Voltage-Lock-Out behavior. If you decide to go down this path, you need to be prepared to do bread-board testing. I want some changes made. |

Why do I need bread-board testing? mike_mike has tested it already. --- End quote --- That's right, the design that mike_mike settled on. I would like to make some minor changes. There are some parts that aren't needed like the op-amp for the CC LED and a few other bits. I like to test a design on a bread-board before making a PCB. Testing on a simulator is ok also I guess, I have never tried it. I can draw a schematic. |

Draw it and I 'll try it on Proteus as it 's a lot easier than the breadboard. Also add the transistors (for 5A output current) in the 'Power block' as in mike_mike 's design they have been ommited. |
