#358 MC34063 Boost Converter Kit

Build and test an MC34063-based boost converter.



The MC34063 is a monolithic DC-to-DC switching controller that can be adapted to step-down, step-up and inverting applications with a minimum of external components.

This module is a very cheap kit designed by ICStation ICSK034A but now available from many sellers on aliexpress, ebay etc.

It has a fixed configuration to boost 5V in to 12V out.

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is just my personal collection of projects. Two main themes have emerged in recent years, sometimes combined:

  • electronics - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting
  • scale modelling - I caught the bug after deciding to build a Harrier during covid to demonstrate an electronic jet engine simulation. Let the fun begin..
To be honest, I haven't quite figured out if these two interests belong in the same GitHub repo or not. But for now - they are all here!

Projects are often inspired by things found wild on the net, or ideas from the many great electronics and scale modelling podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.
