Hello. I want to make an 'aliexpress special' amplifier, with a pi 5, for a home entertainment center. I'd be using a TPA3255, a separate power supply board (45v @ 8.3a) , a pull and push fans config with a pwm controller.
The question is how can I regulate all the components with the differing voltage and current? The op amp will get unfiltered power from the supply but then I could use a step down converter for the pi 5, fans and pwm controller? I'm not the best when it comes to electricity but, is current is only used when needed/drawn? As in there won't be any fans blowing up or anything if they're coming from the same point for the raspberry pi? Perhaps hooking up the two fans to the USB 2 ports?
Thank you
