  • \$\begingroup\$ Nick, you just need a Buck converter in between the 12V out and the 5V-in. So, instead of "can i", ask "how can i", and you will get better success. Specifically, you can ask, "I want to do this:" and change the above picture to include a rectangle with "Buck Converter" between the 12V-out and the 5V-in, and say, "Please help me either pick a buck converter or make a buck converter that will do this." Then provide a "power budget" saying, "each widget draws a max of 0.25 Watt, so I have to provide a max of 10*0.25W=2.5W." And....

No, you can't connect a 12V supply into devices that are rated for only 5V.
