    Help me PSU with output of 0-12V 1A using only discrete components

    Re: PSU design, 0-12V 1A Which area are you referring to when you say the "top circuit"? I don't really understand how the circuit you posted works.

    Help me PSU with output of 0-12V 1A using only discrete components

    Re: PSU design, 0-12V 1A An op amp would be no problem, I just can't use any ICs that have a built in current limiter or something like that.

    Help me PSU with output of 0-12V 1A using only discrete components

    Re: PSU design, 0-12V 1A It is not important that I use that exact circuit, the only requirements are that I only use discrete components to achieve the desired results.

    Help me PSU with output of 0-12V 1A using only discrete components

    I have been trying to design a bench PSU using only discrete components. The input will be 16-20v and I need to output 0-12v 1A with current limiting. So far I have managed to get Q3 and R6 are supposed to control the current limit at 1A but I don't think it is working, where am I going wrong...
