I am working on an audio application which is to be built on a custom board using STM32H723VG and the X-CUBE-AUDIO-KIT V1.1.1.  I have demonstrated a prototype solution using the pre-built AUDIO-KIT binary loaded on the STM32H735G-DK development boar...

I am using a small solar cell to charge a lithium-ion 18650, 3.7V, 2200mAh. I would like to use the SPV1050 in boost mode in order to capture energy at the lower voltages, but the open circuit voltage of the cell goes up to 5.8V, which is well above ...
