This question already has an answer here:
I want to use a power regulator PCB I designed to switch down 60V to 12V and 12V to 5V in order to power a USB plug and use it as a phone charger. My only worry is that the switching regulators I am using (TI TPS54560) can provide up to 5A of current whereas the plug is rated for 1A. Do phones cap their charging current at 1 or 2A on their own or is this something I need to implement in my system in order to avoid damaging them? Thank you for your help!
