Hi everyone,
I'm designing a circuit for which I need to supply dc 5v, 4A (for a rpi3 and some LEDs), 10v, 800mA (for a dc motor) and 36v, 200mA (for a pump module circuit I need to include).
Ideally, I would love to power this with a charging battery to make it portable, but that may be to much for my league (i.e., hobby/dyi person).
On the other hand, to make things simpler from the beginning, I've thought on using a 36v wall plug-in power supply to directly supply the pump module and two different voltage regulators (one for 5v and other for 10v). I've also considered using a lower power supply (12v), easier to find, and step it up to 36v, a down to 10v and 5v. Looked into dc/dc converters, switching regulators, zener diodes designs, etc. Also looked into battery charger/boost/chuck modules...and in the end I've got lost to what is the best solution to supply these three voltages to my circuit.
Can anyone please give me some hints to what would be the best approach so that I can get back on focus on what components to look for? (if it is even possible to get a "simple" battery powered solution, even better).
Thank you in advance for your time.
Best regards,
Peter
