This is a little test to see if I can make this portable lab power supply with voltage and current limiting.
Based on the XL6009 DC-DC converter, which unfortunately is discontinued, but I have some boards and took the IC's off to test it. Probably a one-off project, but this could be replaced with a different IC in the future, if the project is a success.
Designed to fit a KRADEX Z-32 project box with minor modifications.
