I needed a small power supply for my microcontroller experiments which doesn’t take up half my desk:)
So I designed one.
The PSU works with TL494 PWM controller. The current measurement on whole range (10mA..1.5A) was a big challenge for me. I use a 4 channels 12bit D/A to control both TL494.

I like to use KiCad software. Easy to work with it and of course it is an opensource software.

I used
Autodesk fusion 360
for the design. Thanks for supporting personal use for hobbyists.
