Apologies if I butcher the terminology. I'm a new hobbyist trying to learn the rope.
I have 1 power supply that I'd like to use to power 3 devices:
- Commodore 64 motherboard: 9V 1.5 Amps
- Commodore 64 peripherals: 5V 1 Amp
- LCD Module: 12V 2.5 Amps
From doing some research, it looks like I will need at least a 12V, 6 Amp power supply.
From there, I know I need a switching regulator to down step the voltage.
My questions are:
- How do I split the power supply into 3 outputs?
- Once I have it split, do I need 1 switching regulator for each output that needs to be down stepped?
Thanks!
EDIT: The C64 needs 9V AC, not DC as @RJR pointed out.

As long as your 12V source supply can support the total current requirements this is a project that requires two switching regulators.
