Circuit + PCB design for USB Car Power Supply 5.15V 4 AMPS

Circuit Design + Board Design

Basic Description

Car USB Power Supply

Input 10-20 V

Output 5.15 V 4 Amps

Special features :

The USB needs to be able to output 5.15 V @ 4 Amps for 15 seconds

after the input Power has been switched off (maybe via capacitor ?)

There needs to be 1 GPIO pin that is 3.3V as long as input Power is connected

If input Power is disconnected this pin needs to be switched to Ground

The PCB Dimension should be as small as possible and have a USB connector on one side of the PCB and 2 screw terminals for Power and Ground input on the other side of the PCB

The design files as well as the Gerber/Drill/BOM files need to be made available after the Project is finalized

Skills: PCB Layout, Electronics, Electrical Engineering, Circuit Design, Product Design
