    Designing a variable current source

    Hey everyone For the meantime we decided to try the solution summitville offered, a dedicated IC: LT3083 & LT3086. I will update in any changes or progress I will make in them or in the other circuits. Thanks for the help!

    Designing a variable current source

    Hey Here is the simulation I ran: The graph is the Iload vs V1 (Input) I think the problem is with the transistor and OPAMP I chose? I will try to simulate again. Thanks! 31crutschow, Thanks. I will try it as well.

    Designing a variable current source

    Hi, Thanks for clarifying. I looked on your tutorial and tried simulating it at LTSPICE and didn't get any results. I'm still reading about it in various sources. The things I see the most are an OPAMP in which the output is connected to a transistor (BJT or MOS) that opens the current for the...

    Designing a variable current source

    Hey all! Thanks for replying. I'm currently working on specification. All I know for now is that the control voltage should be 0-5V OR 0-10V, preferably to 0-5V. About a block diagram- attached Klaus, What does it mean high side or low side? Thanks again. I will try and go through similar...

    Designing a variable current source

    Hey! I want to design a variable current source, voltage controlled - from 0.1mA to 2.5A. Do you have any tips, circuits, etc? Many thanks!
