Simple 15V, 1.5A, CC/CV Bench Power Supply Circuit - (With Optional Laptop Charger Source) 2018-02-05

It's generally desired that a bench supply have both the voltage and current adjustable from zero (or nearly so) to the maximum. An LM317 is often used to make a simple supply but its minimum output voltage is about 1.25V, which complicates controlling the short-circuit current limit, and it has a dropout voltage of around 2-3V depending upon the output current, which reduces its...
