-Various IC manufactuers have material for understanding power conversion, including switch mode power supplies. These can help advanced users better understand power conversion that you see in the Power Trees included in the Arduino datasheets. See [ON Semiconductor's Switch-Mode Power Supply Reference Manual](https://www.onsemi.com/pub/Collateral/Smpsrm-D.PDF) or the [Power Topologies Handbook by Texas Instruments](https://www.ti.com/seclit/ug/slyu036/slyu036.pdf).
