Hi People
This is a step up dc to dc converter. This schematic inputs a 15V and outputs a 22V DC. However, I want the input range to be between 3V to 50V and all gives the same constant 22V DC output current. How can this be done with UC 3845. I have attached the schematics below and spice files. Can anyone help to edit the schematic and add some components so that the this circuit can take a range of input voltages?
Thank you for reading
