I have a few bits for the car now that need power adaptors, is it possible to make a car adaptor that high 5a+ 20v to 1v?
Would be good with a digi display and turn pot so i can choose the exact voltage i want?
You can use any of the adjustable switch mode step-up ICs such as LM2675adj. Info on this one you can find in: robotica.pardini.net/Documentos/LM2675.pdf
