5V @ 3A Power Supply using TPS54302

Project non tested

This circuit is based on TPS54302, a high efficient buck converter from Texas instrument. The input range for this circuit varies between 4.5V to 28V and it can produce an output voltage of 5V. Over voltage protection and over current protection are the two major advantages of this device.


  • Input(V): 4.5VDC to 28VDC
  • Output(V): 5VDC
  • Output load: 3A
  • PCB:85mm X 31mm
