So I'm working on a motor driver board. Right now the supply voltage to my board is 24VDC, with a 12V buck converter, and 5V and 3V LDO's for logic stuff. My buck converter is limited to around 40V, which makes me wonder, what if I wanted to use a 60VDC or 100VDC power supply? What type of device would I use to convert a high voltage DC supply, which would be used for the motors, to a low voltage supply (3.3V, 250ma or so)?
I know I could just use two DC power supplies, which is essentially converting from AC twice with different size transformers, but there must be a way to do this directly from DC.
Thanks,
Matt
