I'm working on designing a circuit with two distinct loads - one being a DC motor and another being an LED strip. I want to run both off the same power source, but they have different voltage requirements. The strip requires a fixed 5V and the motor will require 12V+.
I'm currently planning to wire them in parallel. My question is, is it better to choose a power source with a higher voltage and add a step down to the LED strip or choose a lower voltage power source and add a step up to the motor? Is there a current impact/trade off between these two options? Is there a trade off in overall power consumption from the source?
If there's not a big trade-off either way, then what criteria should I consider when choosing a power source?
Thanks for the help!
