Altium Schematic and PCB Design. Small PCB to derive multiple isolated DC rails from a 12V switchmode supply.

I have a small project where 5 Canon DSLR cameras are to be powered by a single PCB. The board will be powered by a single 12V 500W Meanwell switch mode supply. This supply will then have to be converted down into multiple 7.5V 2.1A isolated DC rails. It is very important that each rail is completely isolated and component size and cost are kept to a minimum. Input Rail - Power LED - PCB mount Screw Terminals for GND, 12V Each Output Rail - 5 total * Over Current Protection * .PCB surface mount LED to indicate power is active * Suitable PCB mount screw terminal for 0V, 7.5V Project Outputs - Altium Project - Schematic and Component Libraries - Altium Project - PCB and Component Libraries - BOMs (Altium schematic and PCB should be properly created to generate this)
