Hello I am looking at the app note: https://www.st.com/resource/en/application_note/an4449-buckboost-converter-using-the-stm32f334-discovery-kit-stmicroelectronics.pdf
And would like to know if this kind of design can be implemented on the STM32G474. The project design is for average current mode noninverting buck boost converter with potential to add a output sense resistor to turn it into a battery charger.
Regards,
Mike

Welcome @mhuang, to the community!
The STM32G474 can be seen as the big brother of the STM32F334, so that the same and more can be realised with it. There is also discovery kit B-G474E-DPOW1 that use the STM32G474 in this way.
If you feed your favourite search engine with "+STM32G474 +buck-boost", you should find even more projects.
Hope that helps?
Good luck!

Thanks Peter, I have a B-G474E-DPOW1 on the way, but just wanted to make sure I didn't miss any peripheral or firmware level differences that would prevent the implementation. Are the firmware/example project files for STM32F334 compatible with the G474 and vice versa?
