Making a Synchronous Buck-Boost Converter Based on the ATtiny10

Published at : 23 Dec 2025

Here's a simple project I had fun making based on an ATtiny10 and a quad AND gate for dead time generation.

Huge thanks to PCBWay for the great PCBs!

I won't upload the gerbers because the inductor isn't a standard one, and more importantly the device would require improvements (like current control) to be something I would consider being worth reproducing.
